Altra - Glad Hand Seals

Tractor trailer yellow silicone glad hand seals are essential components in pneumatic brake systems. They are typically located at the connection points between the tractor and trailer, ensuring a tight seal and preventing air leakage. These seals are made from yellow silicone, a durable and flexible material that provides excellent resistance to temperature extremes, chemicals, and abrasion.

Uses
