Pneumatic Fitting Types Explained – Full Guide to Air Tube Connectors
Main Types of Pneumatic Fittings Type Example Function Straight Fittings PU / PC Connect tubes in a straight line Elbow Fittings PL / PV Change direction (90°) Tee Fittings PE / PY Split airflow into two directions Cross Fittings PZA Split airflow into multiple directions Bulkhead Fittings PM / PLM / PMF Pass tubes through panels Valves PA / HVSS / HVFF Control airflow Straight Pneumatic Fittings Straight fittings are used to connect two tubes or a tube to a threaded port in a straight line. Common types: PU → tube to tube PC → tube to thread Best for: Simple connections Pipeline extension Low complexity systems Elbow Pneumatic Fittings Elbow fittings allow tubing to change direction (usually 90°). Common types: PL → threaded elbow PV → tube-to-tube elbow Best for: Space-saving installations Direction change in piping Tee Pneumatic Fittings Tee fittings are used to split airflow into two branches. Common types: PE → T-type (90° branch) PY → Y-type (angled branch, smoother flow) Best for: Airflow branching Distribution systems Cross Pneumatic Fittings Cross fittings allow four-way air distribution in complex systems. Common type: PZA → 4-way connector Best for: Multi-line air distribution Complex pneumatic circuits Bulkhead Pneumatic Fittings Bulkhead...
