This coil measures 5\/16\" in cross-section x 22\" in length, which is enough to fully repack a stuffing box with material left over for the next service interval.\u003c\/p\u003e\n\u003cp\u003eLike the rest of the Tefpack series, part number 10033 is built around PTFE, a synthetic material that handles continuous water exposure without swelling, hardening, or breaking down. Compared to traditional flax packing, PTFE runs with less friction against the shaft, which translates to lower operating temperatures at the stuffing box and less wear on both the packing and the shaft over time.\u003c\/p\u003e\n\u003cp\u003eInstallation is the same process used across the Tefpack range: cut each ring at a 45-degree angle for a clean joint around the shaft, stagger successive ring joints 90 degrees apart, and tighten the packing nut evenly. A slight weep during initial break-in is expected and healthy. Once seated, Tefpack holds its compression well and typically requires far less routine adjustment than flax.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWestern Pacific Trading part number: 10033\u003c\/li\u003e\n\u003cli\u003eTefpack PTFE synthetic shaft packing\u003c\/li\u003e\n\u003cli\u003eSize: 5\/16\" cross-section x 22\" length\u003c\/li\u003e\n\u003cli\u003eSmallest cross-section in the Tefpack lineup; fits standard 5\/16\" stuffing boxes\u003c\/li\u003e\n\u003cli\u003eSuitable for smaller 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 10033\u003c\/p\u003e","brand":"Western Pacific Trading","offers":[{"title":"Default Title","offer_id":55565459259697,"sku":"WPT-10033","price":15.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0015\/7184\/8291\/files\/WPT-10037_f6c3e93a-2be7-43a2-9208-bfa3cc4f0b9a.jpg?v=1785684834","url":"https:\/\/www.firstchoicemarine.com\/products\/western-pacific-trading-tefpack-packing-5-16-x-22-10033","provider":"First Choice Marine","version":"1.0","type":"link"}
