Looking to connect a PVC pipe to PEX? Well there are a couple options available to tackle this project. They range from the tried and true threaded adapters to the fast and easy SharkBite fittings. Threaded adapters have been plumbers’ choice for years, but SharkBite has recently come on the scene and has quickly gained traction with homeowners and plumbers alike.
Check out these examples of a threaded adapter (left) and SharkBite fittings (right) in action!
Both applications are fairly straightforward, watch our video below for more details in the process. When you are ready to do this yourself be sure to visit us at SupplyHouse.com for a wide selection of fittings sure to have exactly what you need.

hello
I am doing a new shower system and I am coming out of the wall with 1/2 in pvc…I need to get to the valve which will be outside the wall with a 3/4 in straight thread connection…can you help me with this application…so basically I need to come off the pvc and 90 degree to the 3/4 connection
Hi Gregory,
Do you mind giving me a little bit more information? Does the valve have a male or female connection? Also, just to double check, the threading is straight not tapered, correct?
Ok the valve body is female. So basically I need to come from the supply which is 1/2 in pvc and connect to the valve body with a 3/4 inc male straight thread
Alright, I think I have a solution for you. For the PVC fitting we carry this guy that should work- http://www.supplyhouse.com/Spears-410-005-1-2-PVC-Sch-40-90-Street-Elbow-MIPTxSOC
Unfortunately we do not carry the second fitting you need, but we found something that should work for you on another site here – https://www.fastenal.com/products/details/421410
Let me know if there is anything else I can help you with.
Ok I see that. Isn’t the thread on the pvc piece shown tapered? And the other part isn’t that straight pipe thread. Will those two work together?
The straight adapter’s female connection is tapered so the PVC male end should go into that just fine.
I have a fastenal close to me. I’m going there to try out you recommendation
Great! Let me know how it comes out and if there is anything else we can help you with.
Can I crimps a pex tube to schedule 40 pvc pipe? Using in a lawn sprinkler application.
Hey Tim,
You should use one of the male/female threaded fittings combinations mentioned in this blog post or a PEX to PVC SharkBite fitting. It’s fine to do a pex crimp on the pex side, but you shouldn’t use a standard hose clamp on pex.
Here’s an example of a female pex crimp fitting you can use for that half: http://www.supplyhouse.com/Bluefin-PXF075-3-4-PEX-x-3-4-NPT-Brass-Female-Adapter-Lead-Free
Here’s an example of the SharkBite you can use to make the entire connection: http://www.supplyhouse.com/SharkBite-UIP4016-3-4-CTS-x-3-4-PVC-Sharkbite-Transition-Coupling
Hope this helps!
For a lawn sprinkler drip system: trying to connect an inline valve manifold with a 3/4 inch pvc inlet to a 1/2 inch PEX supply line. Would like to use Sharkbites if possible. I found a 3/4 inch pvc to 3/4 inch push fit sharkbite – now how do I get it reduced to connect to teh 1/2 inch PEX?
Hi Vicki,
So we sell this product (in the link below) that will do the job, but you will need a bit of 3/4 pipe to bridge the gap between the two SharkBites.

are you sure this will work? I don’t think the 3/4″ end will accept PVC (only CPVC). Will it work to glue a male 3/4″ PVC slip connection to the 3/4″ PVC pipe, then connect a 3/4″ FMT to 1/2 ” sharkbite reducing coupling?
Sorry I misunderstood your question earlier. Yes you are correct that won’t work on the PVC end. There is not a single SharkBite that will do the job. If you are determined to use SharkBite then you will need to use a 3/4 CTS x 3/4 PVC SharkBite (linked below) then a short length of either 3/4 PEX, CPVC, or copper pipe, then the reducing coupling I linked before.

I just had (yet another!) outdoor standpipe break off from it’s PVC supply line underground. This is a regular, and very annoying, occurrence.
I’m wanting to find a way to put a flexible joint to make these stand pipes more robust to the occasional bump. Would using a short length of PEX between the steel standpipe and the underground PVC water line work?
PS we have high pressure, running 90-100 psi.
PPS If you have any other solutions or best practices, please clue us in! This is a very common problem.
I’m transitioning from 1′ pvc to 3/4′ pex in an underground situation. The pex will be run in 1 1/4′ pvc (using it as a conduit for 100′). What would you recommend for fittings at the transition point?
