Pro-source PC66-DOT-42 Straight Push-to-connect Brass Fitting

Product Description

The PRO-SOURCE PC66-DOT-42 is a straight push-to-connect tube fitting manufactured from brass. It connects 1/4-inch outside diameter tubing to a female NPT threaded port, eliminating the need for compression sleeves or ferrules on the push-to-connect end. The fitting meets DOT standards, making it suitable for pneumatic and fluid-transfer lines where compliance is required. At 32 millimeters overall length, it provides a compact inline connection. Plumbers, HVAC technicians, and general mechanical contractors install this type of fitting in control-line, instrumentation, and general-purpose tubing runs.

This fitting is intended for general-purpose applications across residential and light commercial systems. Typical uses include pneumatic control tubing, compressed air distribution, and instrument-line connections where a reliable push-to-connect-to-threaded-port transition is needed. The brass construction suits water, air, and compatible fluid service. The FNPT end threads into standard NPT female ports on valves, manifolds, or equipment ports. DOT compliance broadens its acceptable use in regulated pneumatic circuits.

Key Features

• Straight push-to-connect-to-FNPT configuration for quick, tool-free tube insertion on one end
• Brass construction for corrosion resistance and durability in air and compatible fluid service
• 1/4-inch tube outside diameter compatibility on the push-to-connect end
• DOT-compliant construction for use in regulated pneumatic applications
• NPT thread type on the female threaded end for broad port compatibility
• Compact 32-millimeter overall length suits tight installation spaces

Compatibility

Designed as a general-purpose straight push-to-connect fitting for 1/4-inch OD tubing systems terminating at a female NPT threaded port in pneumatic and fluid-transfer applications.

Installation Notes

Plumbers and mechanical technicians install this fitting type. De-pressurize and de-energize the line before removal or installation. Ensure tubing is cut square and deburred before inserting into the push-to-connect end to achieve a proper seal. Apply thread sealant to the NPT threads in accordance with applicable plumbing or pneumatic codes before threading into the mating port.
