Weiss Instruments WEISS-TC-14 Gauge Cock 1/4 in Nptf Brass

Product Description

The WEISS INSTRUMENTS WEISS-TC-14 is a brass gauge cock designed to isolate pressure gauges from process lines in hydraulic, plumbing, and HVAC applications. Featuring 1/4 inch NPTF male-to-female connections on both ends, this fitting allows technicians to shut off flow to a gauge for safe removal, calibration, or replacement without depressurizing the entire system. The unit carries a 200 psi hydraulic pressure rating, making it suitable for a range of low-to-mid pressure service environments. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of fitting as standard practice wherever gauge serviceability is required.

The WEISS-TC-14 gauge cock is used in residential and light commercial systems where pressure gauges are mounted on pipelines, boilers, chillers, hydronic heating loops, and similar pressurized equipment. The 1/4 inch NPTF thread size is the most common gauge port size, making this cock a routine component in gauge manifold assemblies and test point installations. It is suited for hydraulic and water-based systems operating within the rated pressure limit.

Key Features

• 1/4 inch NPTF x 1/4 inch NPTF connections for standard gauge port fitment
• 200 psi hydraulic pressure rating for low-to-mid pressure service
• Brass construction provides corrosion resistance in water and hydraulic fluid service
• Inline shutoff design allows gauge removal without system depressurization
• Compact form factor fits standard gauge manifold and piping configurations

Compatibility

Designed as an OEM-style replacement or new-installation gauge cock for any system using 1/4 inch NPTF gauge ports rated up to 200 psi hydraulic pressure.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the system before threading the gauge cock into the gauge port. Apply appropriate thread sealant or PTFE tape to the NPTF threads per the applicable plumbing or mechanical code before assembly. Do not exceed the 200 psi hydraulic pressure rating of the fitting.
