Parker GSC-2 Compression Tube Union 1/8 in Pfa Ptfe

Product Description

The PARKER GSC-2 is a compression tube union designed to connect two lengths of tubing in a straight-line configuration without the use of tools or solder. The fitting accepts 1/8 inch tube outside diameter and is constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE) materials, making it well suited for applications where chemical resistance and low friction are required. The plastic grip type provides secure tube retention under compression. At 0.05 pounds, the GSC-2 is a lightweight single-piece union used in instrumentation, fluid handling, and process control lines by plumbers, HVAC technicians, and instrumentation mechanics.

This compression tube union is intended for use in tubing systems that carry aggressive chemicals, high-purity fluids, or gases where metal fittings would be unsuitable. PFA and PTFE construction makes the GSC-2 appropriate for laboratory equipment, chemical processing lines, semiconductor fabrication support systems, and similar instrumentation applications. The 1/8 inch tube OD size is common in small-bore instrumentation and sampling lines. Installation requires no flaring, soldering, or special tooling beyond proper tube preparation and a squared, burr-free tube end.

Key Features

• 1/8 inch tube outside diameter compression fitting for small-bore tubing lines
• PFA and PTFE construction provides broad chemical resistance and low permeability
• Plastic compression grip type secures tube without metal contact
• Straight union configuration joins two tube ends in line
• Lightweight at 0.05 pounds — minimal system load in tight instrumentation panels

Compatibility

Designed as an OEM-style replacement or new-installation compression union for 1/8 inch OD tubing in instrumentation and fluid-handling systems requiring PFA or PTFE wetted materials.

Installation Notes

Installation is performed by instrumentation mechanics or licensed plumbers working on chemical or process fluid lines. Before servicing any tubing connection, shut off flow and relieve system pressure completely. Ensure the tube end is cut square and free of burrs before inserting into the compression fitting to achieve a proper seal. Follow applicable plumbing codes and system design specifications for pressure and temperature ratings when selecting fittings for a given service.
