RITE-LOK Pipe Sealant PS77 from 3M, the diversified technology company, has received independent accreditation that it meets the requirements of the Water Regulations Advisory Scheme (WRAS).

The product has been tested by Intertek against the criteria of BS6920:2000 Part 1 (Suitability of non-metallic products for use in contact with water intended for human consumption with regard to their effect on the quality of the water) and found to be suitable for use with hot water of up to 85°C.

WRAS assesses water fittings products to ensure they do not waste, misuse, unduly consume or contaminate the water supply, in order to comply with Regulation 4* of the Water Supply (Water Fittings) Regulations 1999.

The accreditation means that PS77 can be specified and used on any medium to coarse thread water pipe in the UK.

A single-component, medium-strength thixotropic pipe sealant, RITE-LOK PS77 cures quickly on steel pipes when confined in the absence of air between close-fitting metal surfaces.

It is formulated to lock and seal medium to coarse, straight and tapered pipe threads on pipes between 15mm and 80mm in diameter, preventing vibration, loosening and leakage.

Faye Wilson, Business Development Manager, RITE-LOK Business, at 3M, explained: “RITE-LOK PS77 is a high-specification product, designed for the water supply industry, which is versatile and easy to apply. This accreditation confirms its quality and performance and we anticipate strong demand from both specifiers and installers in this sector.”
