Cast Iron DN 20 DIN 3489 Twist Claw Coupling Rp 1'' Female

This cast iron DIN 3489 (similar) compressor claw coupling (42mm distance between claws) has Rp 1 inch female threads. It is very similar to DIN 3489 and is typically connected to a compressor coupling adhering to DIN 3238 for added security from accidental de-coupling. It has threads to connect it to a hose or fitting. It has a DN of 20 mm. Each coupling has two claws at 180 degrees and is typically connected to another claw coupling. To connect, a force pushing them together is required and then the claws are spun to be 45 degrees apart to secure the connection and make a seal. It is suitable up to 10 bar within a temperature range of -40 to 95 °C. It has a NBR (nitrile rubber) seal. It has a galvanic/electrolytic zinc plated surface protection. This compressor coupling is typically used for demanding environments and larger air flows, while still having a quick connection method with a tight seal.

Pros:

• It is similar to DIN 3489.
• It has a galvanic/electrolytic zinc plated surface protection.
• This compressor coupling is typically used for demanding environments and larger air flows, while still having a quick connection method with a tight seal.

Compressor couplings, 42 mm clamp width (DIN 3489 / DIN 3238) series

Our air coupler offering ranges from DN 2.7 - 19 mm for standard plugs and sockets, as well as a variety of safety air couplings, compressor couplings, manifolds, compressor claw couplings, and the CEJN Multilink system. Various connection types are available for each (female threads, male threads, hose pillar, union nut, etc.) with a wide range of min and max pressures. Our non-interchangeable color-coded options give you a clear visual indicator on what lines to connect. The safety air couplings have push-buttons, swivels, and slides as a safety release function. Our 42 mm compressor claw couplings follow DIN 3489 (similar) as well as DIN 3238 (Mody) for safety applications.
