Returns & warranty terms · Shipping detailsDesign standards & application compatibility
Check the exact model, connection type and applicable standard before ordering. A standard referenced in a product description is not, by itself, evidence of third-party certification. Ask us for model-specific documentation if your project requires it.
Design references are not third-party product certifications. Use the model specifications and the fitting or terminal manufacturer's instructions to confirm compatibility.
How manufacturing supports reliability
IWISS manufacturing capabilities include precision machining, heat treatment, assembly and quality inspection, with dimensional measurement and tensile-testing equipment. The inspection method and acceptance criteria depend on the tool and connection application.
Ask us about the specifications or supporting documentation for your model.

PEX press-sleeve selection
Match the stainless sleeve system, fitting, tube and tool size.
Before ordering
- Do not substitute a copper-ring or cinch-clamp tool solely because the nominal pipe size matches.
- Follow the system's jaw positioning, completion and inspection requirements.
Is the sleeve interchangeable with a copper crimp ring?
Do not assume so. The connection method and required tool must match the sleeve and fitting system.
What should I send for a fit check?
Send the product model, cable or pipe size, connector or fitting part number, and clear photos. Include the intended application so our team can help you identify the appropriate setup.
