BC1/4-N3 connects 1/4 in outside-diameter pneumatic tubing to a 3/8 NPT male straight stud connection. The mating port must have the correct thread standard and size.

The straight configuration keeps the tubing aligned with the equipment port and is useful where a direct connection is preferable. Choose an elbow when the line needs to turn immediately at the port.

This model uses a 3/8 NPT male thread for a matching female NPT port. It is not specified as a universal-thread connection.

Match the thread type to the port, use only the approved sealing method for that connection and avoid over-tightening. Insert tubing squarely and fully into the push-to-connect socket.

The published all-metal B-Series range is specified for compressed air and vacuum service, subject to compatible tubing, proper sealing and the limits of the assembled system. Other fluids need separate compatibility confirmation.

The published fitting-family limits extend from full vacuum to 176 psi (12 bar, as listed for the fitting family), with a fitting temperature range of -40 to +248 °F (-40 to +120 °C). Actual system limits also depend on tubing, seals and installation; do not treat these as fluid-compatibility certifications.
