BD1/4-N3 - 1/4 in Tube x 3/8 NPT Nickel-Plated Brass Run Swivel Tee

The Pneuforce BD1/4-N3 is an all-metal nickel-plated brass run swivel tee for 1/4 in outside-diameter tubing and a 3/8 NPT connection. Its run tee layout helps connect pneumatic or vacuum tubing to the correct type of equipment port.

The fitting includes a positive Click-Click grip collar release feature, providing audible and tactile feedback when the collar is depressed during tube removal.

Industrial Nickel-Plated Brass Fitting

This B-Series all-metal fitting is intended for applications where plastic-bodied fittings may not be preferred. Nickel-plated brass provides excellent mechanical strength, corrosion resistance and long service life in demanding pneumatic and vacuum installations.

Typical Applications

  • Running two tubing lines along a cylinder or manifold
  • Connecting a control-air line to a machine port
  • Dividing or joining vacuum line routing in compact equipment
  • OEM machine assembly where port and tube orientation matter

Fitting Function

A run tee places the tube outlets along the required tube route at a threaded port. Branch and run configurations are selected by geometry, not simply by the word tee.

Installation Note: Cut tubing squarely and push the tube fully into the fitting before pressurizing or applying vacuum. To remove tubing, depress the grip collar; the Click-Click release feedback helps confirm the collar has been disengaged for tube removal. Always confirm tubing compatibility for pressure, temperature and media.

Selecting and Installing This Fitting

For BD1/4-N3, match the specified 1/4 in tubing outside diameter and 3/8 NPT mating thread. Do not rely on approximate inch/metric equivalence without checking tubing tolerances. Cut the tubing squarely, insert it fully and leave access to the release collar. Check actual tubing pressure and temperature limits, which may be lower than the metal fitting limits.

Frequently Asked Questions

How is a run tee used?

A run tee connects a threaded machine port to a two-direction tubing run. Its geometry helps route lines alongside a cylinder, valve bank or manifold.

What is the difference between run and branch tees?

The distinction is the position of the threaded leg relative to the two tubing outlets. Check the fitting orientation and installation space instead of selecting from the word “tee” alone.

What tube and port sizes does this model require?

BD1/4-N3 uses 1/4 in outside-diameter tubing with a 3/8 NPT connection. Tube OD, thread standard and port size all need to match.

What should I check before installing a run tee?

Confirm flow demand for the branches, maintain tube bend radii, keep the tube-release collars accessible and seal the thread with a suitable method.

Is this fitting suitable for compressed air and vacuum?

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.

What are the pressure and temperature limits?

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.
