What is the Graco OP155-7 Fitting?
The Graco OP155-7 Fitting, 1/4MPT X 1/4Tube Polyflow is a precision connector designed to join threaded fluid ports to Polyflow tubing systems. It enables a secure transition between 1/4" male pipe threads and 1/4" flexible tubing for controlled fluid delivery in spray and coating applications.
Engineered for reliability, this fitting ensures stable flow transfer while maintaining leak-resistant performance under operating pressure. It is commonly used in systems requiring flexible tubing integration with rigid threaded components.
Its compact design supports clean installation in tight system layouts, improving routing efficiency and reducing connection complexity.
Key Features and Benefits
- 1/4MPT to 1/4" tube Polyflow connection design
- Enables smooth transition between tubing and threaded ports
- Designed for Graco fluid handling systems
- Leak-resistant performance under pressure
- Compact design for easy system integration
