Commercial trucking can put enormous demands on wheel end components. Built to withstand the harshest conditions, the STEMCO® Defender™ hub cap is made from an ultra-durable, corrosion-free, composite material and is available with a permanently bonded, leak-proof window.
Composite materials with stainless-steel reinforcement inserts will not corrode, making the Defender Hub Cap the best composite hub cap on the market.
Available with Sentinel® Technology to reduce contaminant build-up on hub windows, allowing for accurate lube-level readings. Offset sealing boss on the flange provides extremely durable sealing between the hub cap and hub. The exceptional chemical bond between the hub cap body and window provides strength and prevents leaks.
Magnetic plug option pulls abrasive material away from critical components.
