Coilhose Pneumatics 6-253 Male Connector 3/8-18 Npt

Product Description

The COILHOSE PNEUMATICS 6-253 is a brass male connector designed for coolant and fluid line applications in pneumatic and fluid distribution systems. It features a 3/8-18 NPT threaded connection and a 1/4 inch body diameter, providing a reliable threaded interface for joining fluid lines in shop, machine tool, and industrial service environments. The all-brass construction resists corrosion and withstands the demands of coolant fluid service. This fitting is installed by millwrights, maintenance technicians, and fluid system specialists working on cutting fluid, coolant, or pneumatic supply lines.

The 6-253 is suited for use in machine tool coolant systems, fluid distribution manifolds, and industrial pneumatic plumbing where a male NPT connection is required at a 1/4 inch body diameter. Its threaded design allows for straightforward installation into female NPT ports on pumps, manifolds, valves, and fluid line fittings. It is appropriate for both new installations and replacement service in shop and production environments.

Key Features

• Brass construction for corrosion resistance in coolant and fluid service
• 3/8-18 NPT male thread for standard NPT port compatibility
• 1/4 inch body diameter for compact fluid line routing
• Threaded connection type for secure, leak-resistant assembly
• Suitable for coolant, cutting fluid, and pneumatic fluid line applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for coolant fluid line systems requiring a 3/8-18 NPT male connector with a 1/4 inch body diameter.

Installation Notes

Installation should be performed by a qualified millwright, pipefitter, or maintenance technician. Shut off fluid supply and depressurize the line before removing or installing any fittings. Apply appropriate thread sealant or PTFE tape to NPT threads per standard practice and applicable plumbing codes. Do not overtighten brass fittings, as this can crack the fitting body or damage mating port threads.
