Description
Anderson 1-5/8" Standard Test Plug, Open, Pool Winterizing Plug O50
Seal the line, then add air or water pressure through the stem.
Anderson O50 is a standard open plug. It uses the same straight-sided rubber and large wing nut as a closed plug, plus an opening through the center of the stem so you can introduce air or water pressure into the line you are testing or blowing out. Anderson sizes its plugs by diameter; this one is 1-5/8", so measure the opening before ordering.

Open or closed plug?
A closed plug is solid through the center and simply seals the line. An open plug has a hole through the stem, so you can push air or water through the plug to pressure test or blow out the line.
Does this plug screw in?
No. It pushes straight in, and turning the wing nut squeezes the rubber so it expands against the wall of the opening. When a size is listed for female threads, that means the plug seals inside a threaded opening, not that the plug itself has threads.

Let customers speak for us
All I can say is great customer service. Their products are good too
We had the older version and this dropped right in. Great buy!
I can’t wait for my mini Goldendoodle to be buzz for Halloween! It’s not bulky and small that it won’t bother him. He’s 32 lbs and I got the M/L
No issues with it. I received great customer service ensuring I chose the right thing and shipping was really fast.
Can not say enough about the Balboa retro fit system. I’m no expert, but I watched a you tube video and installed it myself. Hot tub is 14 years old and is up and running like new. Very pleased with my purchase. Thank you.
The process was smooth and lights arived as expected. Everything test out in good working order.
Needed to replace the control overlay on our Nordic Impulse hot tub, but could not find out the make or model number of the actual control panel on our tub. By taking measurements and photos or our actual control panel button positions and functions, I was able to narrow down the options. I ordered this overlay as the button positions seemed to be in the right positions, even though the overall size was smaller than the control panel. The overlay works, in that all buttons and functions are in the right place, and the overlay seems to have adhered well to the panel. It is not a perfect match, as it is smaller overall than it should be. But I am happy with the result and will buy an additional identical overlay as a backup in case this one, too, deteriorates at some point. Took a lot of detecting, but the result is successful!
This costume is legit. It has the sparkle, glittery sheen to it like the one used on screen! Very happy with it!!
Excellent service!
PST was great at communicating the status of my order throughout the various stages. I actually did encounter a shipment issue and they handled it without issue. I will be doing business again with them.

My wife has RA and is always uncomfortable. Our hot tub heater failed and all the local shops were not able to assist until November. I was able to order an exact replacement part which was delivered within 3 days the hot tub was up and functioning in three days. I was very impressed with the quality and service.
Good quality just ordered wrong size and also need thicker cover
Fit perfectly, and fast shipping
