The LARSEN SUPPLY CO., INC. 32-2953 is a 1/4 inch stainless steel pipe cap engineered for permanent or temporary termination of pipe runs. Constructed from Type 304 stainless steel and rated at 150 LB, this cap delivers corrosion resistance suitable for demanding plumbing and piping environments. Female pipe threads provide a secure, leak-resistant connection to male-threaded pipe ends. The part is certified lead free, meeting modern potable water and plumbing code requirements. Licensed plumbers and pipefitters rely on fittings like this for clean, code-compliant line terminations in both new construction and retrofit work.
This pipe cap is suited for residential and light commercial plumbing systems where stainless steel corrosion resistance is required. Common applications include capping unused branch outlets, sealing pipe ends during pressure testing, and permanently closing off decommissioned lines. The 150 LB pressure rating covers standard service pressures found in domestic water supply and low-pressure process piping. Each unit ships individually and is packaged in a carded clamshell, making it appropriate for counter or peg display at supply houses.
Designed as an OEM-style replacement fitting for 1/4 inch male NPT-threaded pipe ends in standard 150 LB stainless steel piping systems.
Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and depressurize the line before threading the cap onto the pipe end. Apply an appropriate thread sealant or PTFE tape to the male threads before installation per IPC guidelines. Do not overtighten, as stainless steel threads can gall if excessive torque is applied.
