Parker 12ECR12-316 Compression Tube Union Ss 5800 Psi

Product Description

The PARKER 12ECR12-316 is a stainless steel compression tube union designed to join two compression tube lines in a single inline connection. Rated to 5800 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1200 degrees F, this fitting is built for demanding fluid and gas handling systems. The all-compression end configuration eliminates the need for welding or threading at the connection point, making it a preferred choice for instrumentation, process, and high-pressure service applications where leak-tight tube joints are required.

This union fitting is suited for use in industrial, commercial, and process systems where stainless steel construction is specified for corrosion resistance or high-temperature service. Typical install scenarios include instrument tubing runs, hydraulic test systems, OEM equipment assemblies, and process lines handling aggressive media. Licensed pipefitters, instrumentation technicians, and plumbing professionals working with compression-style tube fittings will encounter this part in both new construction and retrofit applications.

Key Features

• All-compression end connections on both ends for tool-accessible, weld-free assembly
• 316 stainless steel construction for corrosion resistance across a wide range of media
• 5800 psi maximum working pressure rating for high-pressure service
• Extreme temperature range from -425 degrees F to 1200 degrees F
• Inline union shape for straight tube-to-tube connections
• NPT thread standard where applicable to fitting design

Compatibility

Designed as an OEM-style replacement or direct-install compression tube union for systems requiring all-compression stainless steel fittings in high-pressure or high-temperature service.

Installation Notes

Installation should be performed by a licensed pipefitter or instrumentation technician familiar with compression fitting assembly procedures. Depressurize and isolate the tube line completely before disassembly or installation. Compression fittings require proper ferrule seating and should be tightened to the fitting manufacturer's assembly procedure — do not over-tighten. Verify system pressure and temperature ratings do not exceed the fitting's listed maximums before returning the line to service.
