The PARKER 68P-5-2 is a brass compression tube connector designed to join a compression tube fitting to a male NPT threaded port. It features a Compression x MNPT end connection configuration with a 1/8-27 NPTF thread standard, making it suitable for use in fluid and gas distribution systems where a secure, leak-resistant connection is required. Rated to 150 psi maximum working pressure and rated for temperatures from 0 degrees F to 150 degrees F, this connector is built to handle demanding service conditions. The brass construction provides corrosion resistance and durability in a range of media applications.
This connector is used in residential and light commercial plumbing, HVAC, instrumentation, and fluid handling systems. It is typically installed where a 5/16 inch outside diameter tube must transition to a 1/8-27 MNPT threaded port on valves, gauges, manifolds, or control devices. Licensed plumbers, HVAC technicians, and instrumentation technicians commonly specify this fitting in low-pressure pneumatic and liquid systems requiring reliable tube-to-pipe connections.
Designed as a standard compression-to-MNPT connector for 5/16 inch OD tubing with 1/8-27 NPTF threaded ports, suitable for use in plumbing, HVAC, and fluid handling applications where these end connection types are specified.
Installation should be performed by a licensed plumber or qualified technician following applicable codes such as the IPC or IFGC depending on the medium being conveyed. Shut off and depressurize the system completely before installation or removal of this fitting. Hand-tighten the compression nut before applying tool torque to avoid cross-threading, and inspect the tube end for squareness and burrs before assembly. Do not exceed the rated working pressure or temperature limits for this fitting.
