Parker GAFS-64 Compression Female Straight Adapter 3/8 in

Product Description

The PARKER GAFS-64 is a compression tube female straight adapter designed for use in fluid handling systems requiring reliable, leak-resistant tube connections. This fitting accepts 3/8 inch outside diameter tubing and is constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE), two chemically inert fluoropolymer materials suited for aggressive media, high-purity applications, and elevated temperature service. The plastic grip compression mechanism allows secure tube engagement without metal tooling, making it practical for field assembly in tight installations. Plumbers, instrumentation technicians, and chemical process specialists are the primary installers of this fitting type.

This adapter is used in systems where tubing must transition to a female-threaded port or fitting body. Typical applications include chemical dosing lines, semiconductor fab equipment, laboratory fluid systems, ultrapure water distribution, and any service where metal fittings are unsuitable due to corrosion or contamination concerns. The straight adapter configuration provides a direct, in-line connection path with no directional offset, keeping plumbing layouts compact and clean.

Key Features

• PFA and PTFE construction provides broad chemical resistance and compatibility with high-purity and corrosive media
• Compression-style connection accommodates 3/8 inch OD tubing without soldering, brazing, or threading the tube
• Plastic grip type allows hand-tool assembly and minimizes contamination risk in sensitive fluid systems
• Female straight adapter configuration enables direct inline connection to threaded ports or manifolds
• Lightweight at 0.05 pounds, suited for space-constrained or weight-sensitive installations

Compatibility

Designed as an OEM-style compression fitting for use with 3/8 inch OD fluoropolymer or compatible plastic tubing in fluid handling, chemical process, and high-purity plumbing applications.

Installation Notes

Installation is typically performed by plumbers or instrumentation technicians working on chemical, ultrapure, or process fluid systems. Shut off flow and depressurize the line completely before disassembling or installing any compression fitting. Insert tubing fully to the tube stop before tightening the compression nut to ensure a proper seal. Avoid over-tightening, which can crack or deform fluoropolymer fitting bodies; follow the fitting manufacturer's recommended hand-tight-plus-turns procedure when published.
