Union elbow push-to-connect pneumatic fittings connect two tubes of the same diameter at a right angle. Featuring durable thermoplastic (PBT) bodies, fittings are available in a selection of connection sizes (inch or metric).
Push-to-Connect Union Fittings
Category Selection
A wide selection of pneumatic push-to-connect fittings is available for easy termination of flexible tubing. Connections are made by simply inserting the tubing end into the fitting, which is held in place with gripping claws. To release the tubing, press the circular release ring and the tubing can be easily pulled out.
- Large selection of union air fitting styles
- Inch and metric fitting sizes available
- Tough thermoplastic fitting bodies with stainless steel tube gripping claws
- Bulkhead unions are nickel-plated brass
- Release rings are color coded to differentiate between inch (black) and metric (blue) sizes
- For use with air only
- Working pressure: -29.5" Hg to 150 psi
- Working Temperature 32 to 140°F (0 to 60°C)
- All fittings are push-to-connect quick connect and quick release

Union tee fittings connect three flexible tubes of the same diameter in a "T" configuration (two tubes inline and one at a right angle).
- Thermoplastic (PBT) or stainless steel bodies
- Selection of termination sizes, for up to 1/2" and 16mm (outside diameter) tubing
Union Tee Reducer
Union tee reducers connect three flexible tubes, two of which are the same diameter and a third of a different diameter, in a "T" configuration (two same-sized tubes inline and smaller one at a right angle).
- Thermoplastic (PBT) bodies
- Selection of termination sizes, for up to 1/2" and 16mm (outside diameter) tubing
