Dura Product Lines
Dura makes a full line of PVC fittings in Schedule 40 and the heavier Schedule 80: tees, elbows, couplings, reducers, caps and unions, plus PVC ball valves for irrigation and plumbing.
Use Schedule 40 for standard pressure and Schedule 80 where you need extra wall strength; slip (solvent-weld) ends glue together for permanent joints, while threaded ends let you service valves, pumps and equipment later.
Dura PVC FAQ
What’s the difference between Schedule 40 and Schedule 80 PVC?
Both share the same outside diameter, but Schedule 80 has thicker walls for higher pressure and durability (and is usually gray). Schedule 40 (white) is the standard for most irrigation and drainage fittings.
Slip or threaded fittings: which should I use?
Slip (socket) fittings are solvent-welded for a permanent, leak-resistant joint; threaded fittings screw together so you can disconnect valves, pumps and equipment for service.
What is a PVC union for?
A union joins two pipe ends with a removable collar, so you can take a section apart later without cutting. Handy at valves, filters and pumps.
Can Dura PVC fittings be used with other brands?
Yes. PVC fittings follow standard schedule dimensions, so Dura Schedule 40 and 80 fittings mate with standard PVC pipe and other brands’ fittings of the same schedule.
