The LARSEN SUPPLY CO., INC. 32-1505 is a Type 304 stainless steel pipe nipple sized at 1/8 inch nominal diameter by 2 inches in length. It carries a 150 LB pressure rating and is certified lead free, making it compliant with potable water installation requirements. Both ends feature male NPT (National Pipe Taper) threads for direct connection to female-threaded fittings, valves, or pipe couplings. Licensed plumbers and pipefitters install this fitting to connect or extend pipe runs in low- to medium-pressure systems where corrosion resistance is a priority.
This nipple is suited for residential and light commercial plumbing, gas, and instrumentation applications where stainless steel is specified over galvanized or brass. Type 304 stainless provides strong resistance to rust and chemical corrosion, making it a common choice in wet or humid environments, food-service rough-in work, and certain HVAC condensate or process-line connections. The 1/8 inch size is frequently used for instrument ports, gauge connections, and small-diameter branch lines.
Designed as a standard NPT-threaded pipe nipple for use with 1/8 inch female-threaded fittings, valves, and couplings in plumbing, gas, and instrumentation piping systems rated to 150 LB.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the supply line before removal or installation of any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium before making up the joint. Do not over-torque small-diameter nipples, as this can crack fittings or distort threads.
