PE Pressure Pipework Systems

The PPFV mechanical compression range is for use with PE pipework systems in the conveyance of potable water, fluids, and slurries under pressure. MDPE pipes installed with compression fittings are one of the most widely used systems for above and below ground pipework installations. Products are manufactured to the highest quality and approved by recognised testing institutes and certification bodies.

Standards

Individual products are made in accordance with appropriate British & European (EN) Standards. MDPE fittings are produced to ISO 14236, EN12201, DIN 8076, NP45

Quality & Certification

PE pipework products are produced under the ISO 9001 Quality Assurance Management standard, supported with industry recognised approvals and certification such as DWI, DVGW, ACS, NF, WRAS etc. Blue water fittings are DVGW approved, alternative products/approvals are available.

Material

MDPE products (Body/Nut/Insert) use a high-performance polypropylene copolymer. The split Ring is Acetal (POM), O-Rings Nitrile Rubber (NBR).

Chemical Resistance

PPFV compression fittings are manufactured from polypropylene with a split ring made from Acetal and have NBR O-rings, being suitable for water. For chemical applications please refer to the appropriate chemical resistance chart.

Colour

MDPE products are made in a blue colour.

Temperature to Pressure Relationship

Fittings/Valves/Pipe are not to be used for hot water and should not exceed 20°C although they will withstand the same temperatures as polyethylene pipe. With increased temperature adjust pressure down, contact us for details.
