PE PY PZA Pneumatic Fitting Tee Cross Connector Guide

Key Differences Between Tee and Cross Fittings Feature Tee Fitting (PE / PY) Cross Fitting (PZA) Structure 3-way (T or Y shape) 4-way cross Flow Direction 1 → 2 branches 1 → 3 branches Complexity Simple More complex Space Requirement Compact Requires more space Application Basic branching Multi-direction systems What is a Pneumatic Tee Fitting? A pneumatic tee fitting is a 3-way connector used to split one air line into two directions or combine two into one. There are two common types: T-type (PE) → 90° branch Y-type (PY) → angled branch for smoother airflow Tee fittings are the most commonly used connectors in pneumatic systems. What is a Pneumatic Cross Fitting? A pneumatic cross fitting is a 4-way connector that allows air to flow in multiple directions simultaneously. It is typically used in more complex pneumatic systems where multiple air lines need to be connected at a single point. Compared to tee fittings, cross fittings reduce the number of connectors required in multi-branch systems.
