Merit Brass 01616-20 Pipe End Cap 1-1/4 in 316L Ss Butt Weld Sch 10

Product Description

The MERIT BRASS 01616-20 is a Schedule 10 pipe end cap machined from 316L stainless steel and designed to terminate a 1-1/4 inch pipe run with a butt weld connection on both ends. The 316L alloy grade provides low carbon content, which reduces sensitization during welding and improves corrosion resistance in aggressive media including chlorides and mild acids. Weighing 0.235 pounds, this end cap is sized for use in sanitary, process, and industrial piping systems where a clean, flush-welded termination is required. Licensed pipefitters and welding professionals handle installation in both new construction and retrofit applications.

This end cap is suited for residential and commercial process piping, chemical handling lines, food and beverage installations, and marine or coastal environments where standard carbon steel fittings would be vulnerable to corrosion. The butt weld end connection makes it appropriate for systems where threaded or socket fittings are not acceptable and a full-penetration weld joint is specified. The 1-1/4 inch fitting size covers a common intermediate pipe diameter found in industrial and light commercial systems.

Key Features

• 316L stainless steel construction with low carbon content minimizes weld sensitization and intergranular corrosion
• Butt weld end connection on both ends provides a strong, full-penetration joint suitable for pressure service
• Schedule 10 wall thickness balances weight savings with adequate pressure capacity for light to moderate service
• 1-1/4 inch fitting size covers a widely used intermediate pipe diameter in process and industrial systems
• UNSPSC Code 40175300 for procurement and catalog classification compliance

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch Schedule 10 stainless steel butt weld piping systems.

Installation Notes

Installation requires a qualified pipefitter or certified welder following applicable codes such as ASME B31.3 for process piping or ASME B31.1 for power piping. Isolate and depressurize the line and purge any hazardous media before cutting or welding. Proper fit-up, alignment, and purge gas practices are critical when welding 316L stainless steel to prevent oxidation and maintain corrosion resistance at the weld zone. Do not use galvanic-incompatible fittings or fasteners in the same assembly without appropriate isolation.
