BV3/8 connects two 3/8 in tubing sections at 90 degrees without a threaded equipment port.

A 90-degree union can redirect a line in a compact space while avoiding an excessive tube bend that may kink or restrict flow.

A union elbow has push-to-connect openings for tube-to-tube routing; a male elbow also has a threaded connection for a machine port.

Match the specified tube outside diameter, allow clearance to release each tube and avoid vibration or side loads pulling on the connections.

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.
