Product Identity

This Velvac 035007-1 pack supplies fifty nitrile gladhand seals in black for air-brake connections on commercial vehicles. Fleet technicians and owner-operators use them to maintain reliable coupling between tractor and trailer brake lines.

Installation Context

Each seal has an outside diameter of 1 19/32 in, an inside diameter of 5/8 in and a thickness of .36 in, matching standard gladhand faces without a dust flap. The rubber construction resists oil and ozone while compressing evenly under coupling pressure.

Capacity and Limits

Fifty pieces per package cover multiple service intervals or a full fleet refresh. The material handles normal air-brake pressures and temperature cycles but is not rated for hydraulic fluid exposure or extreme chemical environments.

Questions about this item

At what thickness does the nitrile seal begin to compress under sustained clamping?

Each seal is 0.36 in thick and made of nitrile rubber, which resists permanent set during long-term clamping.

How much heat builds up in the rubber when the gladhand stays pressurised all day?

Nitrile handles typical brake-system temperatures without softening, and the 0.36 in thickness dissipates heat across the full-face surface.

Which gladhand flange size matches the 1 19/32 in outside diameter and 5/8 in inside diameter?

The seal fits standard gladhand couplings with a 1 19/32 in OD and 5/8 in ID, so it works with common truck and trailer air-brake fittings.
