The Dura Schedule 40 Reducing Male Adapter is a dual-purpose fitting designed to transition from PVC pipe to a threaded connection while simultaneously changing the line size. With a solvent weld socket (Slip) on one end and Male Pipe Threads (MPT) on the other, this adapter is ideal for connecting Schedule 40 PVC pipe to valves, pumps, or sprinkler heads that have a different thread size than your main pipe run.
By combining a reducer and an adapter into a single unit, you eliminate the need for multiple irrigation fittings, reducing the risk of leaks and keeping your system compact. Whether you are stepping down from a 3/4" pipe to a 1/2" valve, or adapting a 1/2" line to a 3/4" component, this fitting provides a professional, high-pressure seal.

Install carefully to ensure a leak-proof transition.
Step 1: Solvent Weld the Slip Side
Clean and prime the PVC pipe and the adapter's socket using Purple Primer. Apply PVC Glue, insert the pipe fully, and hold for 30 seconds.
Step 2: Prepare the Threads
Wrap the Male Pipe Threads (MPT) of the adapter with 3-5 layers of thread seal tape. Wrap clockwise to prevent unraveling.
Step 3: Connect
Screw the adapter into the female threaded component (valve, filter, or fitting) by hand until snug.
Step 4: Tighten
Use a wrench to tighten one-half to one full turn past hand tight. Do not overtighten, especially if connecting to plastic female threads, as this may cause cracking.
