I know these are not being made anymore. Anyone else aware of anyone else making these or is this something I need to make myself. Not planning to winterize for awhile. Just want to be prepared. I have Groco Sea Strainers on my 320.
 
Esteban, I'm having trouble loading that Groco web page. Do they have a part that is a replacement strainer basket lid with a hose fitting?
 
I was hoping to find something like the thoroflush. I may try to make my own. It's just for winterizing.
 
With the right tools these tops can be easily made from readily available replacement strainer tops. The most difficult thing is the thread cutter.

I know fwebster has the needed parts list and proceedure to make these yourself. Maybe he can share these here??
 
Good idea Alex! I will watch for fwebster's comments.. however if possible I prefer to use readily available stuff to make my own like a simple nylon through hull fitting, 1/4" board and hose. After all, unless I'm missing something it sounds easy enough to make and it's going to sit on a shelf 364 days a year.

Warren, i don't think anyone is making these anymore. I have a couple a good friend made for me for the #4 and #7 tops on my four Perko strainers in the bilge and they work fabulous. :thumbsup:
 
I also had one made. Check out the a/c strainer flush cap thread in Spring Commission forum.
 
Here are pictures of the home made ones I have. A friend made them for me. Supplies can be had at any hardware store, but you need that large thread cutter ...

Great pics Alex, thanks. I am trying to source the caps now. One lead is Hopkins-Carter in Florida. But a 5 day wait - they probably order from Perko. Anyone know who stocks them?

Warren,
If you can find someone to cut holes in the strainer caps and you have all the hardware, why not just use the existing caps? Putting the hose barbs on will not effect the performance of the caps and, once done, they are there when you need them. Only down side is that you have to take them somewhere to be drilled and you can't use your boat during that time......

I would not recommend that. An altered cap with the valve is probably safe, but if something happens to the valve, you have water rushing into your bilge. The cap is very thin at the mounting spot for the valve and not designed really to have threads cut into it. There is very little metal into which to cut the threads. Too slim of a margin for me to leave it on permanently. If you step on it hard, you may break it off. If you leave them on I at least would have a spare pair of caps on hand and close the sea cocks when leaving the boat. I only use mine for flushing and winterization and then put the caps back on.
 
Skolbe, I have everything you need to make those.(tools, taps) Give me a call and don't buy any tools I have everything you'll need at home.
