Frequently Asked Questions
What are PP compression fittings used for?
PP (Polypropylene) compression fittings are primarily used for connecting polyethylene (PE) pipes. They are widely implemented in water supply networks, agricultural irrigation systems, municipal pipe construction, and landscaping installations.
What pressure rating do these fittings support?
Our PP compression fittings are designed to support PN10 pressure standards. This makes them ideal for systems running up to 10 BAR (1.0 Mpa) working pressure, offering excellent safety margins for standard agricultural and household water pipe scenarios.
