R134A O-RING KIT

Item HS/HST70K is a TFE Coated Buna 70A O-Ring Kit built for maintenance, repair, field service and inventory coverage across multiple O-ring sizes. This item should be matched using its material, hardness, product category and item number when dimensional attributes are not provided in the row. The TFE coated Buna-N nitrile (NBR) compound is selected for reduced surface friction with the resilience of Buna-N nitrile material. It is with a listed temperature range of -40°F (-40°C) to 325°F (163°C), which can help narrow material selection for heat, cold or process exposure. The green & blue color and round profile provide a practical visual identifier during receiving, stocking and installation. As an O-ring kit, it supports maintenance coverage, field repair readiness and organized replacement seal selection. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. Key selection details include material, hardness, product type, cross-section, inside diameter, outside diameter and application. These specification details help customers and resellers compare the part by performance requirements rather than brand name alone. Engineers, maintenance teams and purchasing groups can use the listed dimensions to verify fit before selecting the seal for a groove or assembly.
