Velvac Gladhand Seal Red PK4

This four-pack supplies polyurethane gladhand seals in red for commercial vehicle air-brake systems. Each unit features a closed-face design with a 1 13/32 in outside diameter and 5/8 in inside diameter. The seals measure 0.37 in thick and are sold new in a quantity of four.

Emergency-line identification and debris protection

The red colour marks the emergency brake line for quick visual checks during pre-trip inspections. A built-in screen blocks contaminants from entering the air circuit while the closed face maintains a positive seal. No dust flap is included so the screen serves as the sole barrier.

Four-seal kit covers a standard tractor-trailer set

One package provides enough seals for both gladhands on a typical tractor and trailer combination. The polyurethane material resists ozone and temperature cycling in normal fleet service. Operations running larger fleets or requiring dust-flap equipped seals will need additional kits or a different part number.

Questions about this item

Will the 1 13/32 in outside diameter polyurethane seals need periodic replacement due to hardening?

The polyurethane material resists hardening and cracking better than rubber, so the four red seals in the pack typically last through multiple gladhand connection cycles without scheduled replacement.

What stops the 0.37 in thick seals from leaking first when the trailer brakes are applied continuously?

The closed-face design with a 5/8 in inside diameter creates a positive seal against the gladhand face, and the polyurethane holds its shape under sustained air pressure without extruding.

Does the red polyurethane generate extra heat or draw power when the braking system runs all day?

The seals are passive components with no electrical or moving parts, so they add no heat, noise or power draw during continuous operation.
