TR4430 Mid-Length Rigid Metal Valve Extension

Sitting between the shorter and longer options in the lineup, the TR4430 offers a 105.2mm rigid metal extension sized for truck and bus wheel configurations that need more reach than the shortest extension provides but not the full length of the longest.

Like the rest of the series, it's machined as a solid metal piece rather than assembled from multiple parts, which keeps the connection tight and eliminates a common failure point where joints can loosen under vibration.

This mid-length option is a common fit for many standard dual-wheel setups, making it one of the more frequently stocked extensions in a fleet parts inventory. Once threaded onto the stem, it holds the valve at a fixed, easy-to-reach point for every future inflation check.
