Product Summary

Boost efficiency and eliminate hassles with the Haltec DS1-50 Double-Seal Valve Caps — a box of 50 flow-through caps engineered for high-pressure truck and trailer applications. Instead of removing caps to inflate or check pressure, the DS-1 lets your team gauge, inflate, or deflate directly through the cap, saving up to 65% of time compared to traditional valve caps. Made for rugged service, these caps feature a strong all-metal housing with precision brass components, topped with a self-sealing O-ring for tight, reliable sealing. The heat-resistant grommets ensure the seal remains effective even under extended high temperatures. When a core fails, the cap behaves like a check-valve: the seal automatically tightens to preserve pressure and prevent air loss. Each cap in this 50-piece pack is designed with thread size .307-32 (inside thread) and overall length 7/8in. The temperature rating for the seals is ?40°F to +250°F, so whether you’re operating in cold climates or high-heat exhaust areas, these will hold up. With DS1-50, you’ll get fewer lost caps, less downtime, and a leaner maintenance process. Perfect for fleets, repair shops, heavy-haul, trucking, and commercial vehicle maintenance, this box ensures you always have caps on hand.
