Description

Overview

The Air Tank Drain Valve provides a simple, hands-on way to purge moisture from trailer air reservoirs. Because the pull-cable lets you actuate the valve from a safe position, routine draining becomes faster, cleaner, and far more consistent across the fleet.

Features

• Manual pull cable enables remote operation under the chassis
• Fits common 1/4 NPT tank ports for straightforward replacement
• Durable metal valve body designed for workshop service
• Regular draining helps limit corrosion and water-related brake faults

Specifications and Materials

Part number: ABS312.
Thread size: 1/4 NPT male. Cable length: 48in (approx. 1220mm). Body: metal valve with braided pull cable. Use an appropriate pneumatic thread sealant during installation.

Compatibility and Fitment

Install the SCTEG Air Tank Drain Valve into a clean 1/4 NPT port, then route the cable to a reachable location away from moving components. After tightening, perform a leak check and verify reliable purging. This cross-reference listing means this valve is a suitable replacement for the part numbers and applications shown. Some changes in air line plumbing may be required. KN21004, N3613AW, 12104

Compliance and Safety

Always isolate the vehicle, chock wheels, and release system pressure before working on air tanks. Then wear eye protection and gloves. After installation, check all joints with approved leak detection fluid, retorque if necessary, and confirm the tank empties freely. Finally, record the service for maintenance tracking.

Trailer Applications

Use this valve on semi-trailer and dog trailer reservoirs, converter dollies, and other pneumatic tanks that benefit from a manual purge. Because the cable reach improves access, technicians can drain tanks more often, which in turn helps protect valves, air dryers, and brake components.
