Parker’s Fluid System Connectors (FSC) Division has announced an important update to its brass Push-to-Connect (PTC) straight fittings. The new design features a brass sleeve engineered to reduce tubing insertion and release forces, making installation faster, easier, and more consistent across applications.
Improved Design for Better Performance
The updated PTC fittings from Parker include a precision-machined brass sleeve that delivers several key advantages.
- Reduced insertion and release force for easier tubing connections
- More consistent performance, especially in repetitive or high-volume assembly operations
- Better ergonomics, minimizing hand strain for technicians and assemblers
- Smooth and reliable connection feel that enhances the overall customer experience
While no formal industry standards exist for insertion and release force in push-to-connect fittings, Parker’s updated design provides a measurable usability improvement without sacrificing the product’s proven sealing integrity and durability.
