T-H Marine 16700020 Hose Clamps The T-H Marine 16700020 is an Oetiker stepless one-ear hose clamp sized for hose connections in the 15.3 to 18.5mm (0.60 to 0.72 in.) range, made from 304 stainless steel throughout for corrosion resistance in freshwater and saltwater environments. Sold 100 per bag, this is a shop-quantity pack suited for marine service centers, boat builders, and riggers who work with small-diameter hose connections on a regular basis. Oetiker stepless clamps are a factory-standard fastening method used by OEM boat builders and engine manufacturers because they create a uniform, 360-degree seal around the hose without the pressure gaps that can occur with worm-drive screw clamps. The one-ear design is crimped with a pincer tool during installation, permanently locking the clamp at a precise diameter. Once set, the clamp cannot loosen from vibration, thermal cycling, or pressure changes, the way a screw clamp can back off over time. At 15.3 to 18.5mm, this is one of the smallest sizes in the Oetiker marine clamp lineup and is well suited for 3/8 in. to 1/2 in. hose connections, including vacuum lines, small-diameter fuel fittings, and other tight plumbing connections on outboard-powered boats where standard clamps are simply too large to seat properly. Removal requires cutting the clamp off, and a new clamp is needed for reinstallation, which is standard practice for stepless clamp systems. Size range: 15.3 to 18.5mm (0.60 to 0.72 in.) Material: 304 stainless steel throughout Specially formed strip edges reduce contact stress on the hose surface Mechanical interlock supports the use of pre-coated materials and makes tampering visible Requires a pincer tool for installation and a cut tool for removal Sold 100 per bag Normalized SKU: 16700020UPC Code: 733572078206

T-H Marine 16700004 Hose Clamps The T-H Marine 16700004 is an Oetiker stepless one-ear hose clamp sized for hose connections in the 7.8 to 9.5mm (0.30 to 0.37 in.) range, made from 304 stainless steel throughout for corrosion resistance in freshwater and saltwater environments. Sold 100 per bag, this is a shop-quantity pack suited for marine service centers, engine technicians, and riggers who work with very small-diameter hose and tubing connections on a regular basis. Oetiker stepless clamps are a factory-standard fastening method used by OEM boat builders and engine manufacturers because they create a uniform, 360-degree seal around the hose without the pressure gaps that can occur with worm-drive screw clamps. The one-ear design is crimped with a pincer tool during installation, permanently locking the clamp at a precise diameter. Once set, the clamp cannot loosen from vibration, thermal cycling, or pressure changes, the way a screw clamp can back off over time. At 7.8 to 9.5mm, this is the smallest size in the T-H Marine Oetiker lineup and is designed for very fine hose connections, including vacuum nipples, sensor hoses, small vent lines, and other sub-3/8 in. tubing found on outboard engine systems and marine fuel components. Standard clamps cannot be used at this diameter, making this a specialty item for precise engine service work. Removal requires cutting the clamp off, and a new clamp is needed for reinstallation. Size range: 7.8 to 9.5mm (0.30 to 0.37 in.) Material: 304 stainless steel throughout Specially formed strip edges reduce contact stress on the hose surface Mechanical interlock supports the use of pre-coated materials and makes tampering visible Requires a pincer tool for installation and a cut tool for removal Sold 100 per bag Normalized SKU: 16700004UPC Code: 733572074659

T-H Marine 16700001 Hose Clamps The T-H Marine 16700001 is an Oetiker stepless one-ear hose clamp sized for hose connections in the 5.8 to 7.0mm (0.22 to 0.27 in.) range, made from 304 stainless steel throughout for corrosion resistance in freshwater and saltwater environments. Sold 100 per bag, this is a shop-quantity pack suited for marine engine technicians and service centers working with the finest-diameter tubing connections found on modern outboard engines. Oetiker stepless clamps are a factory-standard fastening method used by OEM boat builders and engine manufacturers because they create a uniform, 360-degree seal around the hose without the pressure gaps that can occur with worm-drive screw clamps. The one-ear design is crimped with a pincer tool during installation, permanently locking the clamp at a precise diameter. Once set, the clamp cannot loosen from vibration, thermal cycling, or pressure changes, the way a screw clamp can back off over time. At 5.8 to 7.0mm, this is the finest size in the T-H Marine Oetiker lineup and is intended for micro-diameter connections, including small vacuum nipples, emissions system tubing, sensor port hoses, and other precision fittings on outboard engine fuel and emissions systems where no standard clamp option exists. If you are doing factory-level engine service or rebuilding fuel system components, this is the clamp size that matches OEM specifications at that scale. Removal requires cutting the clamp off, and a new clamp is needed for reinstallation. Size range: 5.8 to 7.0mm (0.22 to 0.27 in.)

EMP 54-01374 Hose Clamps The EMP 54-01374 is a Size 14 hose clamp for outboard, inboard, and sterndrive engine hose applications. It replaces Mercury 4158210 and OMC 329653, covering a wide range of cooling system, fuel system, and general engine hose connections across multiple brands and drive types. Size 14 is a common clamp size used throughout marine engine compartments, and having a few on hand is never a bad idea. Whether you are replacing a clamp that has corroded through, securing a new hose run, or just doing a full cooling system refresh, this clamp fits the bill for the applications listed. It crosses with Sierra 18-8203 for those verifying fitment across suppliers or sourcing from multiple distributors.

EMP 54-01373 Hose Clamps The EMP 54-01373 is a Size #12 hose clamp used across a wide range of outboard, inboard, and sterndrive engine hose applications. It replaces Mercury 415829, OMC 329654, and Volvo 3852196, covering three major OEM lines with a single part number. Hose clamps are one of those parts that seem minor until one fails at the wrong moment. Having the right size on hand before you need it is just good boat ownership. Size #12 is a common spec across cooling, fuel, and bilge hose connections on many marine engines, so it's worth keeping a few in the toolbox.

EMP 54-01372 Hose Clamps The EMP 54-01372 is a Size #10 hose clamp built for outboard, inboard, and sterndrive engine hose connections. It replaces Mercury 415828, OMC 911616, and Volvo 3852529, making it a solid cross-reference across three major OEM lines. Size #10 is a step down from #12 and shows up frequently on smaller diameter cooling, fuel, and bilge hose fittings across a wide range of marine engines. It's the kind of part that costs almost nothing to stock and a lot more to be without when you need it mid-service. It also crosses with: Sierra: 18-8021 Normalized SKU: 5401372UPC Code: 840080419787

EMP 54-01371 Hose Clamps The EMP 54-01371 is a Size #8 hose clamp for outboard, inboard, and sterndrive engine hose connections on 1987 and later models. It replaces Mercury 41582Q7, OMC 322652, and Volvo 3852170, covering three major OEM lines with one part. Size #8 is one of the smaller common clamp sizes and turns up on tighter hose fittings throughout the cooling and fuel systems on many marine engines. If you're doing a full service or replacing hoses, swapping the clamps at the same time is just good practice. This one fits the bill without any fuss.

EMP 54-01369 Hose Clamps The EMP 54-01369 is a Size #4 hose clamp for outboard, inboard, and sterndrive engine hose applications. It replaces Mercury 415821 and OMC 124249, covering two major OEM lines with a single part. Size #4 is one of the smallest common marine hose clamp sizes and is typically found on smaller diameter fuel, cooling, and vent line connections throughout the engine. It's easy to overlook during a service, but a loose or corroded clamp at this size can cause just as much trouble as a larger one. Worth having a few on the shelf. It also crosses with: Sierra: 18-8201 Normalized SKU: 5401369UPC Code: 840080454467

EMP 54-01368 Hose Clamps The EMP 54-01368 is a Size #2 hose clamp for outboard, inboard, and sterndrive engine hose connections. It replaces Mercury 415824, OMC 322653, and Volvo 3852171, making it a cross-reference across three major OEM lines. Size #2 is among the smallest marine hose clamp sizes and is commonly found securing narrow-diameter fuel, vent, and cooling lines throughout the engine. These small clamps tend to get skipped during service, but they hold critical connections in place. Picking up a few extras while you're ordering is never a bad call.
