3-inch Polypropylene Dust Cap
The Banjo 300CAP is a 3-inch Type DC dust cap made from glass-filled polypropylene. It fits male cam-lever couplers with a 3-inch NPT thread to seal out dirt and moisture. Plumbing installers and maintenance crews use it to protect open ports on tanks, pumps and irrigation lines.
100 psi pressure limit
The coupling is rated for a maximum operating pressure of 100 psi. It must not be disconnected while the line is under pressure or still contains liquid. The precision-moulded body and EPDM gasket maintain a reliable seal within that pressure range.
Single-port closure with standard interchangeability
One cap closes a single 3-inch male adapter; it does not join two lines or increase flow capacity. The stainless-steel rings, arms and pins allow the lever to open smoothly by hand. The cap interchanges with other cam-lever brands, so it fits existing polypropylene systems without modification.
