JARO PP equal coupling compression fittings provide a straight, same-size connection for PE and compatible plastic piping. The PP body and four-segment locking ring support practical mechanical assembly without heat fusion or solvent cement, making the fitting suitable for irrigation, water supply, and general fluid-distribution projects.
Key Features & Advantages
Four-Segment Locking Ring
The four-segment locking ring grips the pipe evenly as the nut is tightened, helping the connection adapt to normal pipe outside-diameter tolerances.
Straight Same-Size Connection
The equal coupling joins two pipes of the same outside diameter in a compact inline layout for extensions, repairs, and sectional pipework.
Tool-Free Mechanical Assembly
No heat fusion or solvent cement is required. Cut the pipe square, insert it fully, and tighten the compression nut according to the installation instructions.
PP Body with Seal Options
The PP construction is paired with a standard NBR seal; EPDM can be selected where the project requires a different sealing configuration.
Reinforced Body Structure
Thicker body design with trapezoidal ribs helps distribute installation torque and internal pressure, reducing stress concentration for enhanced structural stability.
100% Virgin Material
Manufactured with 100% virgin PP material to ensure consistent mechanical performance, durability and long-term reliability.
Multi-Directional Grip Ring
Four-claw grip ring design distributes forces in multiple directions, adapting to pipe deformation and dimensional variations for secure locking.

Applications for PP Equal Coupling Compression Fittings
Irrigation Pipe Extensions
Connect equal-size main or branch lines in agricultural and landscape irrigation systems.
Water Supply Distribution
Use for straight pipe runs in compatible low- and medium-pressure water distribution systems.
Pipe Repair and Maintenance
Useful when a damaged section or a serviceable inline joint needs to be addressed without heat-fusion equipment.
FAQ
Find practical answers about JARO PP equal coupling compression fittings. Confirm pipe outside diameter, pressure class, medium, and seal selection before placing an order.
Select the fitting size according to the outside diameter of the compatible PE or plastic pipe. Please confirm pipe material, SDR, and project requirements with the sales team where necessary.
When the nut is tightened, the segments move inward around the pipe. This distributes the gripping action around the circumference rather than relying on a single continuous ring.
Seal selection depends on temperature and the conveyed medium. Provide the operating conditions so the appropriate seal configuration can be confirmed.
Yes. JARO can discuss branding, color, packaging, and project-specific configuration requirements for OEM orders.
