These fittings have a 3/4 inch slip fitting that a short piece of PVC pipe can be glued into. You can then use another fitting that is slip on one side and threaded on the other and use a 3/4 screw cap fitting.

We had trouble using 5/8 plastic fitting due to the outside diameter of plastic fittings, it is thicker than brass ones. We switched to 5/8 brass fittings, they fit the hose perfectly. I would call it 5/8".

The hose barbs are for 5/8" diameter heater hose. The male thread on the brass fitting is 1/4" pipe with 5/8" hose barb.We have installed a couple hundred of these.

They're all 1/4"straight pipe in the cylinder but the fittings are a DIN style I believe

The pipe size of the fitting is about 1/2", which makes the outside diameter of the threaded area close to 3/4"

I would suggest the INSIDE diameter is 1/2 inch. in my case 1/2 inch fittings worked very well, but 5/8 fittings could not be inserted.

Mine was 3/4" and it fit beautifully. There are also fittings that will adapt to several different diameters, as mentioned previously.

The 2", 1 3/4", 1 1/2", 1 3/8", and the 1 1/4" have a 3/8th" shaft. The 1", and the 3/4" have a 5/16th" shaft. The 1/2", 3/8", and 1/4" have a 1/4th" shaft. Hope this helps. Also, we cooled these with oil and it worked well.

Too short for your application, I do not know how consistent they are, but mine is 1 1/8th inch

I beleive they are 3/4". I am not near mine but I remember the hoses being quite large. It allows for plenty of water movement without requiring higher pressure ratings.

I'm using them on my 3/4 heavy duty hoses...the hose connections are the same size on 5/8 & 3/4 hoses.

This filter has (female) 1/4" threaded openings on both ends that accept 1/4 " male fittings. Hope this helps?

This will only work with 3/8" hose barbs. 1/4" is very small hose if you're referring to the threading you need to measure the actual barb on the fitting.

Amy, 1 3/4" is very small. This product is about 5 inches long. I just measured the screw holes and they are exactly 4 inches apart.

Water connections on my unit are 1/2 in. CTS (copper tubing size).Will 3/8 supplys work depends on your incoming water pressure.I have my unit plumbed 1/2 cts. If your 3/8 in. supply lines work on your existing fixtures you are going to be fine

Not sure. They are universal fittings so I am "guessing" that you should be good to go. Sorry I don't have a better answer for you.
