Polypropylene cam and groove Coupling are made according to standard A-A-59326(original standard Mil-C-27487), size from 1/2″ to 4″. Black Polypropylene Camlock fitting s are made from polypropylene reinforced with 25%-30%acid-resistant fibreglass.It has excellent tolerance to most corrosive acids, bases, fertilizers, solvents and wastewater, so it is widely used in inhalation / discharge hoses for agricultural or industrial applications.
Body materials: Polypropylene
Handle: stainless steel
Gaskets：Buna-N (NBR), EPDM
The thread of camlock fittings are BSP,BSPT,NPT
Pressure :50-100 Psi( depending on size and temperature)
