CARBON & STAINLESS STEEL
GAUGE COCKS
Superior Products
The Superior Products Carbon & Stainless Steel Gauge Cocks isolate gauge glass assemblies with an inline vent and drain connection. A forged body is stronger and more reliable than a cast one, and stainless steel internals stand up to corrosive field service in both carbon and stainless versions.
Every valve is 100% hydro-tested to a 1.5x safety factor before it ships, and the design pairs with Superior gauge glass and guards for a complete sight-flow package. Carbon steel suits standard service while stainless handles corrosive and sour conditions.
Rated at 500 PSI working pressure, the gauge cocks use a 1/2" or 3/4" MNPT rigid vessel connection with a 5/8" or 3/4" OD gauge glass connection. Made in the USA.
Typical Applications:
Gauge glass isolation and shutoff, tank and vessel level assemblies, corrosive and sour-service isolation, vent and drain service, and sight-flow indication management.

PERFORMANCE ADVANTAGES
Why the Superior Carbon & Stainless Gauge Cocks Perform Where It Counts
FORGED WITH STAINLESS INTERNALS
The forged body reduces the imperfections common to castings, and stainless steel internals resist corrosion in both carbon and stainless versions. That combination delivers a stronger, longer-lasting gauge cock.
100% HYDRO-TESTED
Every valve is hydro-tested to a 1.5x safety factor before shipment, verifying integrity before it reaches the field. That gives confidence the valve holds on critical sight-flow service.
INLINE VENT AND DRAIN
The integral vent and drain connection lets operators safely bleed and drain the gauge assembly during service. That simplifies maintenance and reduces spill risk.
MATERIAL FOR THE SERVICE
Carbon steel covers standard applications while the stainless version handles corrosive and sour conditions, with NACE-compliant options available. One design spans general and severe service.
