Product details

The Lasco 437-251 is a PVC reducer bushing that takes a 2 in slip socket down to a 1-1/2 in slip socket. Both ends are solvent weld, so it glues in with standard primer and PVC cement.

Where it gets used

Pool plumbing runs mostly in 2 in and 1-1/2 in pipe, and the two sizes meet constantly: at pump ports, at filter and valve connections, and anywhere a run steps down. A bushing is the tidiest way to make that step, because it seats inside an existing 2 in socket instead of adding another fitting and another glue joint.

Check before you glue

Dry fit first and confirm the pipe you are joining is genuinely 1-1/2 in, since threaded and slip fittings of the same nominal size are not interchangeable. This one is slip on both ends.

Questions and answers

What people ask about this product, answered by our pool techs.

Which way does it reduce?
It takes 2 in down to 1-1/2 in. The outside is 2 in, the inside socket is 1-1/2 in.
Is it threaded or glued?
Glued. Both ends are slip sockets, so it goes in with primer and PVC cement.
Is this the same as a 437-249?
No. This listing is 437-251, the 2 in by 1-1/2 in slip by slip bushing. Other numbers in the 437 series are different size combinations.
Can I use it to connect a 1-1/2 in pump to 2 in pipe?
That is the usual reason people buy it. The bushing drops into the 2 in socket and gives you a 1-1/2 in socket to glue the smaller pipe into.
