Value Collection 4CB3/8 Pipe End Cap 3/8 in 304 Ss Fnpt

Product Description

The VALUE COLLECTION 4CB3/8 is a threaded pipe end cap designed to close off the terminal end of a 3/8-inch pipe run. Constructed from 304 stainless steel, it connects via female national pipe taper (FNPT) threads and is rated to 150 psi working pressure. The cap seals open pipe ends during system pressure testing, temporary shutoffs, or permanent line termination. Plumbers, pipefitters, and mechanical contractors install this fitting in plumbing, process, and light industrial piping systems where corrosion resistance and reliable thread engagement are required.

This end cap is suited for residential and commercial plumbing applications, as well as light industrial and process piping where 304 stainless steel is specified for corrosion resistance. Its FNPT threaded connection makes it compatible with standard male NPT pipe ends. Typical uses include capping unused branch outlets, sealing hydronic lines, and terminating compressed air or water distribution runs during phased construction or system modification.

Key Features

• 304 stainless steel construction provides corrosion resistance in wet and mildly aggressive environments
• FNPT threaded connection engages standard male NPT pipe threads for a secure, leak-resistant seal
• 150 psi pressure rating suitable for low- to medium-pressure plumbing and process lines
• 3/8-inch fitting size for common small-bore pipe termination applications
• Compact form factor allows installation in tight spaces near valves, manifolds, or branch tees

Compatibility

Designed as an OEM-style replacement or general-use fitting for standard 3/8-inch male NPT pipe ends in plumbing, hydronic, compressed air, and light industrial piping systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC or IFGC code requirements for the specific service. Depressurize and drain the line completely before removing or installing any threaded fitting. Apply thread sealant tape or pipe compound to the male NPT threads before engagement, and tighten to a firm, wrench-tight fit without over-torquing the stainless threads. Inspect the joint for leaks during system pressure testing before returning the line to service.
