PPH Coupler
The PPH Coupler is a straight-line fitting used to securely join two sections of Polypropylene Homopolymer (PPH) piping. Engineered for reliable performance in aggressive chemical and fluid environments, this coupler ensures a leak-proof, corrosion-resistant joint between PPH pipes of the same diameter.
It is widely used in chemical plants, water treatment facilities, marine applications, and industrial fluid systems throughout the UAE, where durability, thermal resistance, and ease of installation are critical.
