Push-Fit Brass Adapter for 1/4" Tube

This pack of ten brass push-fit adapters connects 1/4 inch outer diameter tubing to a 3/8 inch male NPT thread. The push-to-connect design allows quick assembly without tools, making it suitable for vacuum applications and general pneumatic lines where frequent reconfiguration is required. Each fitting is manufactured from C36000 brass for corrosion resistance.

Pre-Applied Sealant Simplifies Installation

The fittings arrive with thread sealant already applied to the male NPT side, removing the need for separate tape or compound during installation. This reduces assembly time and helps prevent leaks caused by uneven manual sealing. The compact 9/32 inch overall length keeps the connection short, which is useful in tight routing spaces within cabinets or machinery frames.

Rated for 290 psi and 175 °F Operation

The adapters are rated for a maximum operating pressure of 290 psi and a maximum operating temperature of 175 degrees Fahrenheit, covering typical shop air and vacuum systems. They are not intended for hydraulic pressures or temperatures beyond these limits, so engineers specifying high-pressure hydraulic circuits or steam lines should select alternative fittings.
