Actual Socket Diameter of a 3/4" Cross Fitting
Why is are PVC fitting sockets bigger than their named size?
PVC sizes get their name from the inner diameter of the PVC pipe as they are nominal, or 'in name only'. If you add the thickness of the wall on each side of the pipe, the outside diameter of the PVC pipe will always be larger that the actual PVC size.
What will this 3/4" Cross fit?
Important PVC Size Information
This 3/4" Cross Furniture Grade PVC Fitting will fit over the end of standard 3/4" Size Schedule 40 plumbing-grade or Furniture Grade PVC pipe, which has an outside diameter of 1.050" or 1-1/16".
- Connects up to four (4) 3/4" PVC pipe segments for internal support or cross-member reinforcement.
- Pipe inserts inside of the fitting.
- Fits standard 3/4" Schedule 40 PVC pipe.
- Not compatible with CTS or CPVC style pipe, EMT conduit or wood dowels.
How to Use 4-Way PVC Cross Fittings
When to use Standard Crosses
Furniture Grade 4-Way Crosses connect up to four (4) segments of PVC pipe to make internal support or cross-member structures. PVC pipe can be inserted directly into each socket, creating a perfectly flat, heavy-duty, cross connection.
Insert the PVC Pipe into the Cross Fitting
Cut your PVC pipe segments to size, align the PVC pipe with the Cross socket and press it into place. Repeat for the other three sockets. If preferred, you can use clear PVC cement for a secure and permanent fit: Apply a small amount inside the Cross PVC fitting before insertion.
Tap into Place until Fully Seated in the Cross
Tap each PVC pipe until it is fully seated inside the fitting. The pipe should be inserted until it hits the stop or detent inside the fitting. You can then use the Cross in the remainder of your PVC project or build.

Worked great for what I needed. Fit tightly to the pipe, but I was still able to remove.

What can I say? It is one of many Formufit PVC fittings that I use to assemble the frame of a Flight Simulator.

I bought this for an outside bunny cage. Not sure its for outside use, i will let you know if they survive the winter. Other than the uncertainty of it holding up i like it. Plus i was unable to find these in a box store. And of course my store ran out of all the elbows and ts i needed anyway forcing me yet again to online purchase so this purchase was a no brainer.

Not the cheapest, but fit nice and tight with the 3/4" sched 40 pvc from my local hardware store. Used it on the ribs of my greenhouse. Hopefully they'll hold up well.

I used these to make a pvc pipe photo booth out off 3/4 inch pipes. They worked well, just the right fit each time with no funny edges or pieces that were poorly sized like I ran into at the big box stores. I would order again if I didn't now have 10 of them!

This is simply an alternative to the water pipe fitting. At least some big box stores carry this. Looks a little nicer, but that wasn't the main issue--I was building a small "shed" to go inside our chicken pen. Chickens wouldn't care, but I needed the other fittings for some connections. PVC makes a nice building material for such--impervious to rot, light in weight and strong.
