O-Rings & L-Rings

About

O-rings and L-rings are critical sealing components for multi-piece truck, bus, and heavy equipment wheels. These rubber seals sit between the rim base and the side ring or lock ring, creating the airtight seal necessary to maintain proper inflation pressure on tubeless multi-piece wheel assemblies. A worn, cracked, or improperly sized ring is one of the most common causes of slow leaks and air loss on commercial truck and fleet vehicles. Haltec O-rings and L-rings are available in a full range of sizes to fit the most common multi-piece wheel configurations used on semi-trucks, buses, trailers, and heavy equipment. Having the correct replacement rings on hand means leaks get fixed on the first visit rather than requiring a return trip for parts — keeping fleet vehicles on the road and service bay throughput high. Inspect rings during every tire service on multi-piece wheels and replace any that show cracking, deformation, or hardening to prevent air loss and maintain safe operating pressure.
