boeray Glad Hand Seals for Semi Trucks — 40pcs (20 Red/20 Blue), Rubber Universal Fit, Leak‑Proof

boeray glad hand seals are a 40-piece kit of durable rubber gaskets (20 red, 20 blue) designed to restore airtight connections between tractor-trailer glad hands quickly and reliably.

If you run heavy trucks or maintain a fleet, worn glad hand seals lead to air leaks, reduced braking responsiveness, and frequent roadside fixes. These boeray seals use a resilient rubber compound and a tapered base shape so they slip into standard glad hands easily, resist oil and corrosion, and maintain pressure. The dual-color pack helps you match service ports and keep spares on hand so simple swaps get you back on the road fast.

How do boeray glad hand seals stop air leaks?

The seals form a tight barrier inside the glad hand cavity to prevent compressed air from escaping under pressure. Their tapered base and elastic material compress evenly against mating surfaces to maintain a consistent seal during vibration and temperature changes.

• Made from high-grade rubber with oil and corrosion resistance
• Tapered design provides uniform compression for airtight contact
• High pressure endurance so seals hold under operating loads

Will these gaskets fit my truck’s glad hands?

boeray seals are made to a universal profile that fits most standard glad hands used on semi trailers and tractors. They are cross-referenced to common OEM part numbers for easy compatibility checks.

• Compatible with many 37° mounting bracket and heavy-duty shut-off glad hands
• Cross references include Haldex 10028, Tramec 36001, Tectran 10111 and more
• Designed for direct hand installation—no special tools required

How easy is it to replace a glad hand seal in the field?

Replacement is fast and can be done during routine checks or at the roadside without tools. Light lubrication, such as water, can help the tapered base seat fully; once pressed flat the seal sits securely and restores service.

• Quick push-in installation—insert, press flat, and test
• 20 red and 20 blue pieces let you replace multiple seals without delay
• No crimping or adhesive needed, making roadside swaps practical

What durability can I expect from these rubber washers?

The compound and manufacturing process emphasize long service life in harsh commercial environments. They resist oil, corrosion, and repeated use so you won’t be replacing them every few weeks.

• High resistance to oils and contaminants encountered in trucking
• Excellent rebound and shape retention under pressure cycles
• Built to withstand vibration and temperature swings common in fleets

Who is this for: The boeray 40-piece glad hand seal set is ideal for owner-operators, fleet mechanics, and road technicians who need dependable spare gaskets for tractors and trailers. If you want a simple, cost-effective way to eliminate glad hand air leaks, reduce downtime, and keep matching spares on the vehicle, this kit provides immediate replacement capacity with colors that simplify service and organization.
