YiaChuii Glad Hands Replacement Set 3-Pack Blue & Red Aluminium — SAE-Compatible, Durable Rubber Seals

YiaChuii Glad Hands 3 Set pairs heavy-duty blue service and red emergency aluminum couplers with high-quality rubber seals for reliable truck air-line connections.

These glad hands are a replacement set designed for semi trucks and trailers, combining die-cast aluminum construction, a stainless-steel mounting plate with polyurethane color coating, and precision rubber seals. The kit includes color-coded service (blue) and emergency (red) couplers that meet SAE J318 compatibility expectations and fit many common brands. Built for durability, they resist wear, corrosion and fluids while providing a secure, leak-resistant air connection.

How are these glad hands built to last?

The housings use die-cast aluminum for strength and low weight, while the stainless-steel mounting plate increases structural stability and resists rust. Rubber seals are crafted from resilient compounds and finished to withstand oil, water and chemicals without losing flexibility.

• Die-cast aluminum bodies for impact resistance and reduced corrosion.
• Stainless steel plate with polyurethane coating to prevent rust and keep color-coding intact.
• High-quality rubber seals engineered for flexibility and chemical resistance.
• Factory-installed seals included for immediate swap-out or replacement.

Will these fit my truck’s existing fittings?

The set is designed to meet SAE J318 service and emergency configurations and can be used in polarized or non-polarized systems. They are intended as direct replacements for several OEM-style glad hands and compatible with many common couplers.

• Meets SAE J318 service and emergency sizing standards.
• Compatible with Velvac, Tectran, Bendix and many aftermarket systems.
• Polarized and universal mounting options supported.
• Supplied as a red emergency and blue service pair for correct hookup.

How do the seals perform under real-world conditions?

The included rubber seals are processed for durability, maintaining pliability in cold and resisting breakdown from oils, road chemicals and moisture. They aim to reduce air leaks and keep braking systems responsive when installed correctly.

• Oil-, chemical- and water-resistant rubber compounds.
• Precision molding for consistent contact surfaces and better sealing.
• Lightweight and flexible to accommodate repeated connects and disconnects.
• Spare seals included so you can replace worn components quickly.
