The InsulClips allows an uninterrupted vapour seal and eliminates the problem of sweating on metal fittings. This makes the InsulClip the ideal product to secure the installation of the refrigerant pipes, allowing the vapour seal to run the length of the pipework without cutting the insulation material. Made from a composite polyamide (nylon) alloy, which has similar tensile strength properties to nylon but better impact strength, especially at low temperatures.
