Parker 68C-10-12 Brass Compression Tube Connector

Product Description

The PARKER 68C-10-12 is a brass compression tube connector designed to join a compression-end tube to a male NPT threaded port in fluid and pneumatic distribution systems. It features a 3/4-14 NPTF thread size with a Compression x MNPT end configuration, providing a reliable mechanical seal without the need for solder or flare tooling. Rated to 150 psi maximum working pressure and a temperature range of -65 degrees F to 250 degrees F, this fitting suits a broad range of service conditions. Licensed plumbers, pipefitters, and HVAC technicians install this fitting in commercial and industrial piping assemblies.

This connector is well suited for residential and light commercial plumbing, HVAC refrigerant and fluid lines, pneumatic distribution, and hydraulic support circuits where a compression-to-NPT transition is needed. The NPTF thread standard provides pressure-tight engagement through thread interference, making it appropriate for systems that require a dry-seal connection. Typical installation scenarios include connecting copper or compatible tubing to threaded valve bodies, manifolds, or equipment ports.

Key Features

• Brass construction resists corrosion in water, air, and compatible fluid service
• 3/4-14 NPTF thread delivers a pressure-tight dry-seal connection
• Compression x MNPT end configuration allows tubing connection without soldering or flaring
• Rated to 150 psi maximum working pressure
• Wide temperature range: -65 degrees F to 250 degrees F
• Single-piece unit sold individually — no assembly required

Compatibility

Designed as an OEM-style compression-to-MNPT transition fitting for plumbing, HVAC, and pneumatic systems that use 3/4-14 NPTF threaded ports and compatible compression tubing ends.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Shut off and depressurize the system fully before removing or installing any fittings. NPTF connections rely on thread interference for sealing; inspect threads for damage before assembly and apply appropriate thread sealant per system requirements and applicable codes such as the IPC or IFGC. Do not overtighten, as brass threads can be damaged by excessive force.
