Fitting with rubber washer and compression

Reliable connections for drip irrigation systems

When setting up drip irrigation mainlines, the connection point between the tubing and the emitters is the most vulnerable spot for leakage. The Palaplast fitting with a rubber seal and compression nut addresses the common failure points found in standard, lower-cost connectors. Unlike simple barbed fittings that rely solely on friction and hole precision, the Palaplast design utilizes a compression nut mechanism to guarantee a watertight seal regardless of minor installation variances.

Engineered for performance

The standout feature of this Palaplast component is the compression nut. While standard fittings can loosen or eject due to pressure spikes or the thermal expansion/contraction of PE pipes in the sun, this model locks the rubber gasket firmly against the pipe wall. This creates a mechanical hold that remains secure throughout the entire irrigation season.

• Durability: Manufactured from high-grade virgin polypropylene, these fittings include UV stabilizers to prevent embrittlement, ensuring they last 3-5 seasons under direct sunlight.
• Installation: Requires a standard 16mm hole. The nut is tightened by hand, ensuring quick deployment without special tools.
• Seal Integrity: The tapered rubber gasket design effectively compensates for wall thickness variations in irrigation tubing.

Who should choose this product? This fitting is designed for growers who prioritize system uptime and efficiency. If your irrigation setup experiences pressure fluctuations or you are using mid-range wall thickness tubing, the Palaplast fitting is an economically sound choice. It eliminates the frequent need for mid-season maintenance caused by weeping connections, which often plague cheaper, friction-only alternatives.

Considerations: Due to the compression nut, the overall profile is slightly larger than a standard barbed insert. Additionally, if you operate a seasonal system that requires annual disassembly, it is crucial to keep the rubber gasket clean during storage, as debris can affect the sealing surface the following year.
