Series 21 Straight-Through Coupling (without valve) - Plastic Tube Connection - POM (Delrin)

Parker Series 21 Straight-Through Coupling – Reliable Solution for Low-Pressure Applications

The Series 21 coupling from Parker is a straight-through female coupling specifically designed for applications featuring plastic tube connections. Constructed from polyoxymethylene (POM), also known as Delrin, this coupling type offers a robust and reliable solution for low-pressure fluid systems.

Without an integrated valve, this model is ideal for simple, direct fluid transfers in industrial and commercial systems. The POM material provides:

• High chemical resistance
• Excellent wear resistance and durability
• Lower weight compared to metal alternatives
• Cost-effective solution

The coupling is well-suited for pneumatic systems, small hydraulic installations, and other low-pressure applications where plastic components are acceptable. Compatibility with various hose diameters makes it flexible for different installation scenarios.
