Description

Overview

The Drain Valve M22 lets technicians quickly purge moisture from trailer air reservoirs, and it does so with a simple pull-ring action. As a result, routine draining becomes faster, safer, and more consistent across your fleet. Moreover, the metric M22 thread suits common European-style air tanks used on trailers.

Features

• Pull-ring operation enables quick manual draining under the chassis
• Metric M22 male thread for straightforward installation on compatible tanks
• Compact, robust body designed for workshop conditions
• Regular use helps reduce corrosion and water-related brake faults

Specifications and Materials

Part number: AB8312M22.
Thread: M22 male, metric. Typical application: air reservoir drain port on heavy vehicle trailers. Material: metal body with ring pull. Install with pneumatic-grade thread sealant and tighten to the tank maker’s specification.
For regulatory context on heavy vehicle air brake reservoirs and draining practices, see this government bulletin on air brake drain valves.

Compatibility and Fitment

Confirm your tank has an M22 metric port before purchase. Then clean the port, apply suitable thread sealant, and fit the SCTEG Drain Valve M22. After tightening, charge the system and check for leaks with approved leak detection fluid.

Compliance and Safety

Always chock wheels, isolate the vehicle, and release system pressure before opening any tank. Consequently, technicians avoid sudden discharge and debris. After installation, verify the drain path is clear, test the valve several times, and record the service for maintenance tracking.

Trailer Applications

Use this valve on semi-trailer and dog trailer air reservoirs, converter dollies, and other pneumatic tanks where a manual purge is preferred. Additionally, the pull-ring allows placement where access is tight, which encourages more frequent draining and therefore helps protect brake valves and dryers.
