Doesn't matter as long as you can put it inline with the water supply. Union one one side and 1/2" npt on the other.

Is description correct?

The description says sweat by sweat. Mine has a sweat union (inlet) and a 1/2 FPT (outlet). One of the reviews indicates FPT. Is the description wrong? My model number is S1156F, but I can't find that on your site.
Asked by: Landlord

Rated 5 out of 5 by from Exact the replacement Replaced the old pressure regulator and pressure is now 10 to 15 lbs.

Rated 5 out of 5 by from It's what I needed. The one I had clogged with rust and stopped working. Installation was easy. Unscrew the old one, screw on the new one. Back to normal. It was shipped to my home at no extra charge.

Rated 5 out of 5 by from Watts 1/2 in. Cast Brass SWT x SWT Pefect Replacement I bought this water pressure regulator to replace the broken one on my furnace. It came with the gasket used on the larger side. The swap was very easy, took all of 5 minutes, a perfect fit without any issues. You will only need some tape dope for the nipple that threads into one side, so make sure you have some before you start. I would have included photos but doesn't seem like it would be a benefit.

Rated 1 out of 5 by from Product is worthless. This was the 4th time I had to install this product. Pressure level kept varrying.
