Parker 393PDSS-6-6 Compression Shutoff Insert 316 Ss

Product Description

The PARKER 393PDSS-6-6 is a shutoff type insert fitting designed for compression-to-compression tube connections in fluid and pneumatic line assemblies. Constructed from 316 stainless steel, this insert provides reliable shutoff functionality at working pressures up to 150 psi. Its compression x compression end configuration allows for a secure, leak-resistant connection without the need for soldering or special tools. Licensed plumbers, HVAC technicians, and industrial pipefitters commonly install this fitting in applications where tube line isolation or shutoff capability is required at a connection point.

This shutoff insert is suited for use in residential and light commercial plumbing, HVAC refrigerant-adjacent tubing systems, and industrial fluid handling lines where 316 stainless steel corrosion resistance is specified. The compression x compression end style supports common tubing configurations and allows installation in tight spaces where inline shutoff control is needed. It is sold individually and ships as a single unit.

Key Features

• 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• Compression x compression end connections for tool-accessible, solder-free installation
• Rated to 150 psi maximum working pressure
• 1/2-24 straight thread size for precise fitment
• Operates across a temperature range of 0 degrees F minimum to 149 degrees F maximum
• Compact shutoff insert design suitable for inline tube line isolation

Compatibility

Designed as an OEM-style replacement or direct-install shutoff insert for compression tube systems requiring a 316 stainless steel fitting with compression x compression end connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician familiar with compression fitting assembly. Shut off all fluid or pneumatic supply to the line before disassembly or fitting replacement. Ensure tubing ends are cleanly cut and deburred before seating into the compression fitting to prevent leaks. Follow applicable IPC or facility-specific piping codes when installing in pressurized systems.
