Watts 1/8 in LF-NPT-TC Test Cock

This Watts test cock is a bronze component sized at 1/8 in with NPT threading for use with Watts Series LF-NPT-TC backflow preventers. It meets ANS and ASME A 112.1.2 standards and arrives new. The part provides a test point on potable water assemblies.

Check compatibility before ordering

Verify that your backflow preventer is a Watts Series LF-NPT-TC unit accepting a 1/8 in NPT test cock. Confirm the thread type and size match the existing port on the device. Ensure local plumbing codes accept this standard for the intended installation.

Bronze build with NPT threads

The bronze body resists corrosion in water supply environments and handles typical system pressures. NPT threads create a tapered seal that tightens with a wrench, so apply suitable thread sealant during installation. The small 1/8 in profile fits tight mechanical rooms without extra clearance.
