Parker S23 Pneumatic Coupler 1/4 in 300 Psi Stainless Steel

Product Description

The PARKER S23 is a female NPTF threaded pneumatic hose coupler designed for industrial compressed air and pneumatic fluid systems. Built from stainless steel with a zinc chromate finish, it provides corrosion resistance in demanding service environments. The coupler features a 1/4 inch body diameter, a 1/4-18 NPTF thread size, and a maximum working pressure of 300 psi. It follows the Industrial Interchange standard, making it broadly compatible with pneumatic tooling and equipment that uses that coupling configuration. Licensed HVAC technicians, industrial maintenance professionals, and pneumatic system installers use this type of fitting when connecting air lines to tools, valves, and pneumatic actuators.

The PARKER S23 is suited for both light industrial and heavy-duty maintenance applications where stainless steel construction is required for corrosion resistance or sanitary compliance. It is appropriate for use in compressed air systems, pneumatic control circuits, and similar low-to-medium pressure fluid power lines. The Industrial Interchange format is one of the most widely used coupling standards in North American industrial facilities, making this coupler a common replacement or service fitting in shop and field environments.

Key Features

• Stainless steel body with zinc chromate finish for corrosion resistance in harsh environments
• 300 psi maximum working pressure rated for standard industrial compressed air service
• Female NPTF thread provides a pressure-tight mechanical seal without sealant tape on proper mating threads
• Industrial Interchange coupling type for broad compatibility with standard pneumatic tooling
• Operating temperature range of -40 degrees F to 250 degrees F supports a wide range of service conditions
• Compact 1.83 inch overall length suits tight installation spaces

Compatibility

Designed as an OEM-style replacement or service coupler for Industrial Interchange pneumatic systems using 1/4-18 female NPTF threaded connections.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic system service. Depressurize and lock out the air supply completely before removing or installing any pneumatic fitting. NPTF threads are designed to seal on the thread form itself, but confirm thread engagement and system pressure requirements before returning the line to service. Follow applicable facility safety procedures and any relevant compressed air system codes during installation.
