Heavy-Duty Self-Venting Brass Air Cut-Off Valve (M18 x 1.5 Threads, One-Way Exhaust)

KEY FEATURES

• Solid Forged Brass Construction & Wear-Resistant Durability

Crafted entirely from premium, thickened solid brass. Unlike cheap iron or copper-plated alternatives that degrade and rust, our heavy-duty valve is engineered to withstand extreme vibrations, high road pressure, and harsh weather conditions, offering an exceptionally long service life.

• Innovative One-Way, Dustproof Self-Venting Port

Say goodbye to dangerous, high-pressure blowouts during disconnects. This valve features a built-in self-venting mechanism that automatically and safely discharges residual downstream line pressure when closed. The exhaust port is designed with a one-way dustproof seal—allowing air out but strictly blocking dust, moisture, and road debris from entering.

• Upgraded Rust-Proof Sealed Core for Zero-Leak Integrity

We have upgraded the internal valve core to a heavy-duty reinforced carbon steel core treated with a high-performance rustproof coating. This solves the common issue of brass cores deforming and leaking under high pressure. Combined with premium sealing gaskets, it guarantees 100% airtight reliability and high tensile resistance.

• Precision-Engineered CNC Threads (M18 x 1.5)

Featuring silky-smooth, precisely cut threads on both the M18x1.5 external male thread and the rotatable internal female hex nut. The high-precision fit ensures zero-wobble assembly, prevents cross-threading, and makes installation fast and secure.

IMPORTANT NOTE

1. Size Verification Required: Please measure and verify your truck's air line fitting size before purchasing. This valve is strictly sized for M18 x 1.5 metric threads.

2. Proper Seal Prep: Ensure all threads are clean of dirt or debris before installation. It is highly recommended to wrap external threads with high-quality PTFE thread sealant tape to ensure a 100% leak-free connection.

3. Flow Direction: For the self-venting mechanism to operate correctly, ensure the valve is installed in the correct flow direction so the line venting port discharges pressure from the downstream system.
