mcnamara9 Posted August 19, 2008 Share Posted August 19, 2008 As part of my leaping arches, I've noticed when I put 2 pieces of PVC together (1 pipe has the end coupling), they are very dificult to pull apart when you are done using them. I have to use a hammer and screwdriver to pry them off.So I'm trying to figure out what I can apply to the pipes before hand to make them easier to come apart. Any suggestions?I've thought of WD-40 or Vaseline, but not sure if they will break down the plastic in the PVC pipe. Does anyone know? Link to comment Share on other sites More sharing options...
Shubb Posted August 19, 2008 Share Posted August 19, 2008 I used WD-40 last year and had no issues with the pipe. I did use grey electrical conduit instead of the white "sprinkler" pipe so I'm not sure if that makes a difference.Scott Link to comment Share on other sites More sharing options...

PipefitterDan Posted August 19, 2008 Share Posted August 19, 2008 Plumbers grease, most hardware stores should carry it and it's safe for use on PVC.Dan Link to comment Share on other sites More sharing options...
Geoff Harvey Posted August 20, 2008 Share Posted August 20, 2008 HiLast year I used vasolene on my arch joints. To ensure the joints remained in place through the season, I also tightened a stainless steel screw pipe clamp around the circumference of the joint. There was no deterioration of the PVC and the joints separated easily after I removed the pipe clamps.Regards - Geoff Link to comment Share on other sites More sharing options...
Dr. Jones Posted August 20, 2008 Share Posted August 20, 2008 You can try SRS (silicone release spray) food grade - it doesn't deteriorate plastic or rubber and it washes clean with water Link to comment Share on other sites More sharing options...
evan.a Posted August 20, 2008 Share Posted August 20, 2008 antiseize- it use by auto mechanics to keep the bolts from sticking or rusting and is easier to remove bolts later. a must for all mechanics...*note to self- very hard to remove if you get it all over your hands. must use mechanic soap (soap with sand),gojo, or orange degel to clean off hands.

ranger_391xt Posted August 23, 2008 Share Posted August 23, 2008 Petroleum Jelly (a.k.a. Vaseline) works well. Link to comment Share on other sites More sharing options...
Vic Fortenbach Posted August 24, 2008 Share Posted August 24, 2008 I just use some heavy grit sandpaper to sand down the end of the PVC pipe. Still fits together tight, and come apart easer. Link to comment Share on other sites More sharing options...
mcnamara9 Posted August 25, 2008 Author Share Posted August 25, 2008 WOW, thanks everyone for the feedback. This weekend I tried your suggestions and it worked out much better. Thanks again. These forums are great! Link to comment Share on other sites More sharing options...
Dennis Cherry Posted August 25, 2008 Share Posted August 25, 2008 Another way is just cut a slot in the PVC end that fits into the beveled end. 1 to1 1/2" Long.This is the way I built 6 arches. No mess with lubricants.Use a hacksaw or Band saw. Just the thickness of the blade.Dennis Link to comment Share on other sites More sharing options...
