Combined with a quick disconnect shut off valve, this item can save boaters significant money as your heat exchanger will sit idle with freshwater vs saltwater. A must have for me.

Fits well in my Graco strainer and has simplified winterizing my AC system.

Great uses for flushing different things in different ways on a boat. But, Got Dang why they so high. I won’t say they’re not worth the money because they are to me. I’ve bought 3 of em. But dayum, a little plastic cap that someone threaded the center out of and screwed in a garden hose nipple !!!! Why the hell couldn’t I have thought of that and invented it first. Lol. Anyway, highly recommended.

The Trac Ecological 1285-A FLUSHcap is an essential tool for efficiently winterizing marine equipment. It fits perfectly on my Groco ARG-750-S 3/4" Raw Water Strainer. The setup is straightforward: close the freshwater valve, attach a hose and a bucket filled with marine antifreeze, and let the system circulate the antifreeze through. This method ensures that everything is thoroughly winterized. Once finished, simply swap the FLUSHcap with the original cap, and your equipment is ready for the cold season. This small tool makes a big difference in maintenance ease.

This was the easiest way to winterize my Volvo Penta deisel sailboat engine.I have a raw water filter installed in front of the water to the right of the impeller. I just changed it to a 90 degree elbow and with quick connectors and it was the fastest and cleanest way!

Works well, but as it comes it is not setup for a garden hose. It comes with a plastic male garden hose fitting, so you will at least have to buy a female to female coupler in order to be able to attach the male end of a garden hose. I ended up buying a stainless steel ball valve with 1/2” NPT threads on one end (this goes where the white plastic piece once was) to a garden hose fitting on the other end. Then I put a stainless steel quick connect garden hose fitting on that. Now I can move my flush hose from the quick connect for the motors, down into the bilge for the air conditioner flush
