Crimping sleeve - 10/1,3 IVAR.O PPSU8 IC

Product detailed description

This crimping sleeve is part of a press-fit system used in radiant floor heating and cooling applications. It is commonly installed in residential and commercial buildings where low-temperature heating or cooling is required. The sleeve ensures a secure and leak-free connection between the pipe and the fitting, supporting long-term system integrity under thermal cycling conditions. Installers working with IVARCLIMA systems will find this component essential for connecting distribution manifolds to the radiant tubing network.

The installation typically involves preparing the pipe ends, positioning the sleeve over the pipe, and then applying the crimping tool according to the manufacturer's instructions. The system operates with water-based media and requires careful alignment and crimping to avoid misalignment or deformation that could compromise the seal. The sleeve is not intended for use in high-pressure steam or aggressive chemical environments.

Technical parameters

Material	PPSU
Operating temperature	+95 °C
Nominal pressure	PN 10
Code	PPSU8RV
Brand	IVAR

These parameters define the operational limits and material suitability of the sleeve. The nominal pressure rating of PN 10 ensures compatibility with standard low-pressure hydronic systems, while the maximum operating temperature of +95°C aligns with typical heating and cooling circuit requirements. The PPSU material provides resistance to thermal expansion and ensures long-term durability in wet environments.Installation and connection To install the crimping sleeve, first ensure the pipe is cut cleanly and free of burrs. Slide the sleeve onto the pipe before inserting it into the fitting. Use a calibrated crimping tool to apply the required deformation, ensuring even pressure is applied around the circumference. Check that the crimp mark is fully visible and that the sleeve remains aligned with the fitting. Common mistakes include using incorrect tooling, reusing sleeves, or crimping at an angle, which can lead to leaks or premature failure. Always verify the fit after crimping and before system pressurisation.Compatibility and accessories This sleeve is specifically designed for use with IVARCLIMA press-fit fittings and radiant floor heating/cooling systems. It must be used in conjunction with compatible press-fit fittings and crimping tools. Additional components such as manifold sets, valves, and tubing should be sourced according to the system design specifications. Related products include IVARCLIMA press-fit valves and manifold assemblies.Technical background for designers The sleeve functions by deforming around the pipe when a crimping tool is applied, creating a mechanical joint that resists fluid leakage. PPSU (Polyphenylsulfone) is a thermoplastic with high heat resistance and good chemical stability, making it suitable for long-term exposure to water and antifreeze solutions. The system integrates into radiant floor heating and cooling circuits where uniform heat distribution is critical. The sleeve’s performance is influenced by correct installation, ambient operating conditions, and the quality of the mating surfaces on the pipe and fitting.Service and operation During operation, inspect the connections periodically for signs of leakage or deformation, particularly after system commissioning and during seasonal start-ups. There are no scheduled service intervals specified for this component. Ensure that the system is drained and depressurised before performing any maintenance work. Avoid using sharp tools near the crimped joints to prevent accidental damage.Frequently asked questions
