Merit Brass SW3416D-02 Pipe End Cap 1/8 in 304 Ss

Product Description

The MERIT BRASS SW3416D-02 is a socket weld pipe end cap designed to terminate the flow at the end of a 1/8-inch pipe run. Constructed from 304 stainless steel, it delivers a pressure rating of 3,000 psi, making it suitable for demanding fluid and gas piping systems. The socket weld end connection provides a strong, leak-resistant joint when properly fillet welded by a qualified tradesperson. Plumbers, pipefitters, and mechanical contractors install this fitting in systems where a clean pipe termination is required without threaded connections.

This end cap is used in residential and commercial piping installations where 1/8-inch pipe ends must be permanently sealed. It is well suited for hydraulic, pneumatic, steam, and process piping applications that require corrosion-resistant fittings under elevated pressure conditions. The socket weld design is common in tight-space installations where threading is impractical and a welded joint offers superior mechanical integrity.

Key Features

• 304 stainless steel construction resists corrosion in wet and chemical environments
• 3,000 psi pressure rating supports high-pressure piping systems
• Socket weld x socket weld end connection for a strong, permanent joint
• 1/8-inch fitting size for small-bore pipe termination
• Compact, low-profile cap design fits tight installation spaces

Compatibility

Designed as an OEM-style replacement and standard fitting for 1/8-inch socket weld piping systems requiring 304 stainless steel end caps rated to 3,000 psi.

Installation Notes

Installation should be performed by a qualified pipefitter or plumber in accordance with applicable ASME and local mechanical codes. Isolate and fully depressurize the piping system before fitting installation. Socket weld fittings require proper fillet welding by a certified welder; do not use this fitting as a press or compression fitting. Allow all welds to cool and perform a pressure test before returning the system to service.
