These Tubular Valves feature an improved design for sealing tubular glass. The 1/8" thick o-ring provides for easy installation of the glass and requires less wrenching of the packing nut to seal. All valves are supplied with 316 Stainless Steel valve stems, ball checks and glass packing washer. The bodies are precision cast investment castings with each body pressure tested to assure quality. Pressure and temperature ratings for the valves will be determined by the limitation of the tubular glass.

A Special Note About Corrosion
- Excessive corrosion may result in leakage, glass breakage, and premature valve failure.
- Be sure all wetted components of the gauge are constructed with materials compatible with the service medium.

Sightflow does not make chemical compatibility recommendations.
