The coil measures 3\/8\" in cross-section and 22\" in length, giving you plenty of material to fully repack your stuffing box with enough left over for the next service.\u003c\/p\u003e\n\u003cp\u003eTefpack is a PTFE-based synthetic packing that outperforms traditional flax in nearly every practical way. It does not absorb water, does not swell or compress unevenly, and holds its shape through seasons of use without hardening or cracking. The lower friction of PTFE against the shaft also means less heat generated at the stuffing box, which is good news for both the packing and the shaft itself.\u003c\/p\u003e\n\u003cp\u003eInstallation follows standard stuffing box procedure: cut each ring at a 45-degree angle so the ends meet cleanly around the shaft, stagger the joints 90 degrees between rings, and compress evenly with the packing nut. A small weep during initial break-in is normal. Once Tefpack is seated, it typically needs far less follow-up adjustment than flax, which is one less thing to check on every trip out.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWestern Pacific Trading part number: 10034\u003c\/li\u003e\n\u003cli\u003eTefpack PTFE synthetic shaft packing\u003c\/li\u003e\n\u003cli\u003eSize: 3\/8\" cross-section x 22\" length\u003c\/li\u003e\n\u003cli\u003eFits standard 3\/8\" stuffing boxes on inboard and inboard\/outboard applications\u003c\/li\u003e\n\u003cli\u003ePTFE construction runs cooler and lasts longer than flax packing\u003c\/li\u003e\n\u003cli\u003eResistant to swelling, hardening, and water absorption\u003c\/li\u003e\n\u003cli\u003eCut rings at 45 degrees and stagger joints 90 degrees for best seal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eNormalized SKU:\u003c\/b\u003e 10034\u003c\/p\u003e","brand":"Western Pacific Trading","offers":[{"title":"Default Title","offer_id":55565467451697,"sku":"WPT-10034","price":20.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0015\/7184\/8291\/files\/WPT-10037_62d114af-d23f-4c4f-ab71-e0442425516f.jpg?v=1785684769","url":"https:\/\/www.firstchoicemarine.com\/products\/western-pacific-trading-tefpack-packing-3-8-x-22-10034","provider":"First Choice Marine","version":"1.0","type":"link"}
