Parker GAFS-48 Female Straight Adapter 1/4 in Tube Od

Product Description

The PARKER GAFS-48 is a compression tube female straight adapter designed to create a secure, leak-free connection between a 1/4-inch OD tube and a female-threaded port. Constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE), this fitting delivers exceptional chemical resistance and low friction characteristics suited to demanding fluid-handling environments. The plastic grip-style compression mechanism allows for consistent tube seating without the need for solder, flare tooling, or thread sealants. Plumbers, instrumentation technicians, and industrial maintenance professionals install this type of fitting in systems carrying corrosive media, ultra-pure fluids, or aggressive chemicals where metal fittings would be unsuitable.

This adapter is well-suited for use in chemical processing lines, laboratory fluid systems, semiconductor fabrication equipment, and high-purity water distribution. Its straight female configuration makes it a standard choice when transitioning from tubing runs to threaded valve bodies, manifolds, or panel-mount fittings. The PFA and PTFE construction also makes it appropriate for food-grade and pharmaceutical process lines where material purity and non-reactivity are required by specification.

Key Features

• PFA and PTFE construction provides broad chemical resistance across acids, solvents, and oxidizers
• Accepts 1/4-inch OD tubing via compression-style grip for tool-minimal assembly
• Female straight adapter configuration for direct connection to threaded ports or fittings
• Plastic grip mechanism reduces galling risk and is compatible with plastic and PTFE tubing
• Non-reactive materials support use in ultra-pure, pharmaceutical, and food-grade fluid systems

Compatibility

Designed as an OEM-style compression fitting for use with 1/4-inch OD plastic or PTFE tubing in chemical-resistant fluid systems.

Installation Notes

This fitting is typically installed by instrumentation technicians or plumbers working on chemical or high-purity fluid lines. Before installation, shut off all system pressure and purge the line of any residual fluid. Verify that the tube end is cut square and fully seated against the compression stop before tightening the fitting body. Avoid overtightening, as PFA and PTFE components can deform under excessive torque and compromise the seal.
