Universal Gladhand Seal

The Velvac 35163 is a polyurethane gladhand seal designed for universal fit in air-brake connections on commercial vehicles and trailers. It provides a reliable barrier against moisture and debris at the coupling point. Fleet maintenance teams and owner-operators use it to maintain brake-system integrity during regular service intervals.

Pack Quantity and Material Thickness

Each package contains 200 black full-face seals with a material thickness of .37 in and an inside diameter of 5/8 in. The bulk count supports high-volume shops that replace seals on multiple tractors and trailers during scheduled preventative maintenance. The polyurethane construction resists cracking and compression set over repeated coupling cycles.

Coupling Interface Constraints

The seal is engineered for standard gladhand faces without an integrated dust flap, so it seats directly against the mating surface when the connectors are locked. It does not accommodate oversized or non-standard gladhand profiles that exceed the 5/8 in inside diameter. Installers must verify that the existing gladhand bodies match this universal pattern before fitting the seals.

Questions about this item

Will these 5/8 in seals fit the gladhands on my older trailer brake lines?

The 5/8 in inside diameter matches standard gladhand ports, so they install on existing brake connections without adapters.

How can I confirm the 0.37 in thick polyurethane seats correctly after installation?

Press the full-face seal into the gladhand; the black polyurethane should sit flush with no visible gap around the port.

Does the PK200 pack include any dust flaps or mounting hardware for the seals?

The pack contains 200 black polyurethane seals only; dust flaps and gladhand bodies are sold separately.
