Parker 2C-E Pneumatic Coupling 1/4 in 3/8-18 Mnpt Tru-flate

Product Description

The PARKER 2C-E is a threaded pneumatic hose coupling connector designed for compressed air lines in industrial and automotive service environments. This connector uses a 3/8-18 MNPT thread and features a 1/4-inch body diameter, placing it in the Parker Series 10 lineup. Constructed from zinc chromate-finished steel, it handles working pressures up to 300 psi and temperatures from -40 degrees F to 250 degrees F. Licensed technicians and shop maintenance personnel install this fitting when building or servicing pneumatic tool lines, air supply manifolds, and compressed air distribution systems.

This coupling is designed for the Tru-Flate Automotive interchange, making it a direct-fit option for shops already running Tru-Flate-style quick-disconnect systems. Typical install scenarios include air hose assemblies at compressor outlets, pneumatic tool drops in production facilities, and service bay air supply lines. The threaded NPT connection allows a secure, leak-resistant joint when properly sealed with thread sealant or PTFE tape. Overall length is 1.72 inches with a hex size of 0.69 inches, making it compatible with standard open-end or adjustable wrenches.

Key Features

• Tru-Flate Automotive interchange for drop-in compatibility with existing Tru-Flate quick-disconnect setups
• 300 psi maximum working pressure rated for compressed air service
• 3/8-18 MNPT thread for a standard, leak-resistant connection
• Zinc chromate steel construction for corrosion resistance in shop environments
• Wide temperature range: -40 degrees F to 250 degrees F
• Compact 1/4-inch body diameter suits tight pneumatic plumbing layouts

Compatibility

Designed as an OEM-style replacement or new-installation connector for compressed air systems using the Tru-Flate Automotive interchange standard with 3/8-18 MNPT threaded connections.

Installation Notes

Installation is typically performed by licensed pipefitters, HVAC technicians, or qualified shop maintenance personnel. Depressurize and bleed the air line completely before disconnecting or installing any pneumatic fitting. Apply thread sealant or PTFE tape to the male NPT threads before assembly and tighten with a wrench to the hex flats — do not use the body as a wrench contact point. Follow applicable compressed air system codes and the compressor manufacturer guidelines for system pressure limits.
