Parker 210P-2 Pipe Lock Nut 1/8 Inch Fnptf 1000 Psi Brass

Product Description

The PARKER 210P-2 is a brass pipe lock nut designed for securing and locking threaded pipe fittings in fluid and pneumatic systems. It features a 1/8 inch female FNPTF (Female National Pipe Taper Fuel) thread and is rated for a maximum working pressure of 1000 psi. The operating temperature range spans from -65 degrees F to 250 degrees F, making it suitable for a wide range of industrial service conditions. Licensed plumbers, pipefitters, and mechanical contractors typically install this hardware when assembling or servicing threaded pipe connections that require a positive locking interface to prevent loosening under pressure or vibration.

This lock nut is used in residential and commercial plumbing, pneumatic, hydraulic, and fuel line applications where a 1/8 inch FNPTF threaded connection must be secured against movement. Its brass construction offers corrosion resistance in water, air, oil, and mild fuel service environments. Typical installation scenarios include instrument connections, gauge ports, and small-bore pipe assemblies in mechanical rooms, equipment panels, and process piping systems. This product is sold individually and must be ordered in a minimum quantity of 5 units.

Compatibility

Designed as an OEM-style replacement or new-installation hardware for threaded pipe assemblies requiring a 1/8 inch FNPTF lock nut in fluid, pneumatic, or fuel line service.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or mechanical contractors using standard pipe wrenches or open-end wrenches sized to the fitting flats. Shut off and depressurize the system completely before removing or installing any threaded pipe hardware. Apply thread sealant appropriate to the service fluid and verify compliance with applicable codes such as IFGC or IPC where fuel or potable water service is involved. Do not overtighten brass fittings, as the material is subject to cracking under excessive torque.
