Test Cock for Backflow Devices

This Apollo test cock is a low-lead bronze valve designed for use with testable backflow prevention assemblies. It provides a dedicated access point for pressure testing and maintenance verification. The unit is supplied new and meets low-lead material requirements for potable water applications.

1/8 in x 1/4 in MNPT x FNPT Connection

The valve features a male NPT inlet of 1/8 in and a female NPT outlet of 1/4 in to match standard test ports on backflow bodies. Its compact 1 5/8 in length and 1 in width allow installation in tight mechanical rooms. The bronze construction handles a maximum pressure of 175 psi across a temperature range of 33 to 180 degrees F.

Suits Plumbers and Facility Maintenance

This component suits technicians who need a reliable test port for routine backflow certification. It is not intended as a primary shut-off valve or for continuous flow control. Buyers requiring different connection sizes or a full port ball valve configuration should select an alternative fitting.
