Parker L222P-8-8 Brass Pipe Adapter 1/2 in Mnptf X Fnptf

Product Description

The PARKER L222P-8-8 is a brass pipe adapter designed to connect male NPT (MNPTF) threads to female NPT (FNPTF) threads in a 1/2 inch by 1/2 inch configuration. This fitting transitions between threaded connections in pressurized piping systems and is rated to 1000 psi. Constructed from lead-free brass, it meets potable water service requirements. Plumbers, pipefitters, and HVAC technicians install this adapter in water supply lines, gas distribution systems, and general fluid handling applications where a standard NPT thread transition is needed.

This adapter is suited for residential and light commercial plumbing installations where a 1/2 inch male-to-female NPT threaded connection is required. Common applications include water supply line extensions, manifold connections, and service valve installations. Its lead-free brass construction makes it appropriate for potable water systems subject to lead-free compliance mandates under NSF and state plumbing codes. It ships in single-unit packaging, making it practical for service calls and small repair jobs.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and local plumbing code requirements. Shut off water supply and depressurize the line before removing or installing any threaded fittings. Apply thread sealant tape or paste appropriate for the service fluid before making up NPT connections. Do not overtighten brass fittings, as this can crack the fitting body or damage mating threads.
