Category buying guide

Start push-in fitting selection from tube outside diameter and body shape.

Push-in connectors look simple, but the quote depends on tube OD, thread size, straight or elbow direction, branch style, reducer route, panel pass-through need, and whether the installation calls for plastic, brass, or stainless body details.

Choose by connection job

Start with how the air line connects.

Pick the closest fitting use case, then confirm tube OD, thread, body shape, material, pressure, and installation clearance before RFQ.

Scenario 01

Connect a pneumatic tube to a valve, cylinder, or manifold.

Confirm tube OD, male or female thread, and straight or elbow direction before quoting.

Recommended option

PC, PCF, PL, PLF, or related push-in threaded fitting route.

  • Tube OD
  • Thread standard
  • Body direction
  • Material

Common fitting uses

Where pneumatic fittings solve connection details.

Fitting use 01

Valve manifold tube connections

Use straight, elbow, tee, Y, reducer, and manifold fittings to connect valve outputs to cylinders, grippers, sensors, and branch circuits.

  • Standardize tube OD
  • Confirm port thread
  • Keep elbow direction clear

Fitting use 02

Repeated machine build tubing

Use one fitting family across repeated machines so tube OD, thread, elbow direction, and spare fittings stay consistent from build to build.

  • Group by body shape
  • Share quantity by size
  • Confirm plastic, brass, or stainless body
PC Series Male Straight Pneumatic Push-in Fittings (One-Touch) product image
Fitting use 03

Panel pass-throughs and branch points

Use bulkhead, tee, reducer, and elbow fittings where tubes cross panels, split branches, or turn inside tight machine spaces.

  • Measure tube OD
  • Check panel thickness
  • Confirm straight, elbow, tee, or reducer

Connection flow tools

Calculate tube ID, air velocity, and pressure drop before selecting fittings.

Use these tools when fitting selection depends on tube outside diameter, thread, line velocity, pressure loss, or flow-unit communication.

Category FAQ

Common questions before sending an inquiry.

01Push-In Pneumatic FittingsWhat information helps Bepto Pneumatic quote push-in pneumatic fittings?

Tube outside diameter or hose size, thread standard, body shape, pressure range, material preference, installed environment, and quantity are the most useful starting details.

02Push-In Pneumatic FittingsCan Bepto Pneumatic match an existing fitting from photos?

Yes. Send photos from the tube side, thread side, and installed position, plus a tube or thread measurement if available.

03Push-In Pneumatic FittingsWhy are fitting products grouped separately?

Each fitting function has different selection details. Grouping push-in, flow-control, metal, hose barb, and muffler products separately makes tube size, thread, pressure, material, and RFQ details easier to compare.
