## Long description

RECTUS Hose Quick Coupling model 35304 is a compact connector designed for hoses with a 9 mm inner diameter. The coupling combines brass metal parts and durable plastic components to provide a reliable detachable connection for pneumatic and fluid lines. Its compact form factor and straightforward design enable quick hose changes and minimize downtime in workshop, maintenance, and light industrial environments.
Advantages
The brass/plastic construction offers a balance of corrosion resistance and reduced weight, while precision mating surfaces ensure a tight, leak-resistant joint. The coupling is engineered for frequent connect/disconnect cycles, delivering consistent sealing performance and easy manual handling. Its compact dimensions make it suitable for installations with limited space and for retrofitting existing hose runs.
Suitable for
 Pneumatic lines and air tools with 9 mm inner-diameter hose
 Low-pressure fluid transfer and workshop coolant lines
 Maintenance tasks requiring frequent hose replacement
 Compact installations and retrofit applications
Key specifications
 Compatible hose inner diameter: 9 mm
 Materials: brass metal parts and engineered plastic components
 Connection type: quick-release coupling for removable hose joins
 Suitable media: compressed air and non-corrosive fluids (subject to chemical compatibility)
 Design: compact profile for limited-space mounting
How to use
Ensure the hose has a 9 mm inner diameter and is in good condition. Push the hose onto the coupling until it seats firmly against the internal stop, and engage the quick-coupling mechanism according to the assembly orientation. For pneumatic systems, pressurize the line gradually and inspect the joint for leaks. To disconnect, relieve system pressure and operate the release mechanism to separate the coupling halves. Follow workplace safety procedures and use appropriate personal protective equipment when working with pressurized lines or fluids.
Usage recommendations
Use the coupling within the recommended pressure and temperature ranges of the connected system and verify chemical compatibility of the plastic components with the media. Regularly inspect sealing surfaces and replace any worn or damaged parts to maintain leak-free performance. For critical applications, test assemblies under controlled conditions before putting them into regular service.
