Joins 90mm PVC stormwater pipe to 75mm pipe in a straight line, so a 75mm downpipe line can run into a bigger 90mm run to the pit or the street.
It's a Holman PVC stormwater coupling with a 90mm end and a 75mm end, and the pipe goes in and gets glued with PVC primer and solvent cement. It's fine above or below ground, and the joints want 24 hours to reach full strength before you put any load on the line.
Sold each. Full specs are in the tabs below, and if you're working out what a run needs, call us on (08) 8536 4333 or come in and chat with us at 34-52 Milnes Rd, Strathalbyn.
