Unior Zlaczka R 1/4" coupling fitting, model 617797

Unior Zlaczka R 1/4" coupling fitting, model 617797 is a compact 1/4-inch coupling designed for reliable fluid or pneumatic connections in workshop, maintenance and industrial environments. It provides a standard mechanical interface for joining hoses, pipes or tools to a 1/4" threaded port. The fitting is intended to enable quick, leak-resistant connections where space is limited and a consistent seal is required.

Advantages

The coupling fitting offers a standardized 1/4" connection that fits common hoses and tools, ensuring compatibility across a range of systems. Its compact form factor reduces installation space and simplifies routing in tight assemblies. The design prioritizes secure engagement and a durable seal to minimise leakage during operation. Materials and construction are chosen for mechanical stability under typical workshop and light industrial pressures.

Suitable for

• Workshop air and fluid lines
• Maintenance and repair tasks requiring quick hose changes
• Connections for pneumatic tools with 1/4" ports
• Industrial installations with standard 1/4" fittings

Key specifications

• Connection size: 1/4" (inch) threaded coupling
• Application type: fluid and pneumatic connections
• Form factor: compact coupling fitting for inline attachment
• Compatibility: designed for hoses, pipes and tools with 1/4" ports
• Typical environments: workshop, maintenance, light industrial use

How to use

Ensure the mating threads and sealing surfaces are clean and free of debris before installation. Thread the 1/4" coupling into the corresponding port by hand until engagement is secure, then tighten to the required torque using an appropriate wrench if specified by the system. Confirm the connection is seated evenly and test under low pressure to check for leaks. For pneumatic tools, attach the hose or tool connector and verify proper locking or sealing mechanism engagement.

Usage recommendations

Use compatible thread sealant or tape where system practice requires, and avoid overtightening to prevent thread damage. Inspect the coupling periodically for wear or deformation, and replace if sealing performance decreases. For applications with higher pressures or aggressive media, verify material compatibility and workplace specifications before selection.
