Parker 394PD-6-6 Compression Double End Shutoff Coupling

Product Description

The PARKER 394PD-6-6 is a compression tube double end shutoff coupling designed for use in fluid and pneumatic line assemblies. This fitting provides a positive shutoff at both ends of the connection, allowing lines to be disconnected without significant fluid loss or system depressurization. Rated for a maximum working pressure of 150 psi and a temperature range of 0 to 150 degrees F, the 394PD-6-6 is suited for demanding plumbing and fluid-transfer applications. Licensed plumbers, HVAC technicians, and industrial piping professionals are the typical installers of this fitting type.

This coupling is appropriate for residential and light commercial fluid-handling systems where compression-style tube connections are standard. Its double end shutoff design makes it particularly useful in maintenance situations where quick disconnection is required without draining an entire line. It is compatible with compression tube configurations and fits into applications where controlled shutoff during service or replacement is a priority.

Key Features

• Double end shutoff design prevents fluid loss at both ends when disconnected
• Maximum working pressure of 150 psi for a broad range of fluid-transfer applications
• Operating temperature range of 0 to 150 degrees F
• Compression tube fitting style for secure, leak-resistant connections without soldering
• Compact coupling format suited for tight plumbing and fluid-line installations

Compatibility

Designed as an OEM-style replacement or service fitting for compression tube line assemblies operating within 150 psi and 0 to 150 degrees F temperature limits.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician familiar with compression fitting assembly. Shut off and depressurize the system completely before disconnecting or installing this coupling. Use appropriate compression tube tools to ensure proper ferrule seating and a leak-free joint. Verify that all connected tubing is clean, cut square, and free of burrs before assembly.
