Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • Commercial truck tires with standard threaded valve stems
  • Trailer tires with standard threaded valve stems
  • RV and motorhome tires with standard threaded valve stems

Product Overview

Fleet tires lose valuable service time when every pressure check requires removing a tiny cap. DS-1 caps allow checking and adding air through the installed cap while adding a second seal if the valve core begins to seep.

Creates a double-seal closure on compatible valve stems and supports flow-through inflation for faster routine pressure maintenance. This listing is organized around the actual repair decision: what failed, what the part does, which applications are known, and what must match before purchase.

Confirm standard external valve-stem threads, adequate wheel access, and the pressure requirements of the tire system; these caps do not repair a damaged stem or loose core.
