Merit Brass 3616D-02 Pipe End Cap 1/8 in 316 Ss Fnpt

Product Description

The MERIT BRASS 3616D-02 is a threaded pipe end cap designed to close off the open end of a 1/8-inch female NPT pipe connection. Constructed from 316/316L stainless steel, this fitting is rated to 3,000 psi and provides reliable termination in piping systems where corrosion resistance and pressure integrity are critical. The FNPT thread engagement ensures a secure mechanical seal without the need for welding or additional fittings. Plumbers, pipefitters, and industrial maintenance technicians install this type of cap when blanking off a branch, test port, or unused outlet in a pressurized line.

This end cap is suited for use in residential and commercial plumbing, instrumentation, process piping, and fluid handling systems where 316 or 316L stainless steel is specified for corrosion resistance. Typical applications include chemical, marine, and sanitary installations where carbon steel fittings are not acceptable. The 1/8-inch size makes it a common choice for small-diameter branch lines, gauge ports, and vent connections.

Key Features

• 316/316L stainless steel construction for superior corrosion resistance in harsh environments
• Rated to 3,000 psi for use in high-pressure piping applications
• FNPT threaded end connection for straightforward installation with standard NPT male pipe threads
• 1/8-inch fitting size suitable for small-diameter branch and instrumentation ports
• Threaded design allows removal and reinstallation without cutting or welding

Compatibility

Designed as an OEM-style threaded pipe end cap compatible with standard 1/8-inch male NPT pipe threads in 3,000 psi-rated stainless steel piping systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. Depressurize and isolate the piping system completely before installing or removing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads per the system fluid and pressure requirements. Verify torque and leak-tightness after pressurizing in accordance with applicable IPC or system design specifications.
