- Haltec TV-540, TV-550 and TV-570 valve applications
- Commercial truck, bus, trailer, and fleet tires using compatible threaded valve stems
Product Overview
Removing and reinstalling tiny caps across a tractor-trailer wastes time and invites lost caps. The DS-1 lets a technician check or add air through the installed cap while its internal seals provide an additional barrier if the valve core seeps.
The cap threads onto a compatible high-pressure valve and opens to an air chuck or gauge. It is not a substitute for replacing a known bad core, stem, or wheel, but it adds a secondary seal and keeps the valve covered between services.

- Flow-through design allows pressure checks and inflation without cap removal
- Double-seal construction provides secondary protection beyond the valve core

Frequently Asked Questions
Q: Can I inflate the tire without removing the DS-1? A: Yes. Its flow-through design is made for checking and adding air through the installed cap.
Q: Does the double seal mean I can ignore a leaking valve core? A: No. The cap adds protection, but a known failed core or stem should still be repaired.
Q: How should fitment be confirmed before ordering? A: Use the compatible list as a starting point, then compare the original reference number, dimensions, connections, mounting details, production date, and equipment or engine serial information.
Q: Is this supplied by the original equipment manufacturer? A: This is a new aftermarket part. The brand and model names identify the applications it is intended to service.
