1/2 in. 0.700 O.D. Compression Coupling

A:  These will not leak unless you are using them with the wrong king of tubing. If they are leaking you are most likely using a Dig brand coupler with Rainbird brand tubing.

A:  I have the 0.7 tubing and the 0.7 coupling. The tubing was already damaged, split lengthwise about an inch. That split made the tubing flex a bit to a slightly smaller diameter, made it much easier to cram tubing and coupling together.

A:  I believe rainbird’s tubing is smaller than .700 OD so the C33 compression coupling will not work for your repair. I would recommend using our universal nut lock coupling C53. If you have any further questions please contact our technical service/product support line at 1-800-322-9146.

A:  There is no easy way. If you are careful you can heat up the end of the fitting with a lighter and see if that helps.

A:  You don't have to get it fully inserted. 1/4 to 1/2 inch will do. Easier when warm and wet.

A:  Fill a coffee cup with very warm water NOT boiling and insert the ends (one at a time) for a few seconds then insert into the coupling while slowly rotating and pushing. There will be a tight fit so push hard.

A:  Just push. Push it real good.

A:  spit on the tube

A:  wet the tubing

A:  Something I've done in the past is put the poly irrigation line in the hot sun for awhile to make it more malleable (in the winter really hot water works too)

A:  No, this fitting is only for (low pressure) drip tubing, and it should not be used on a sprinkler system.

A:  These couplings only work with 1/2" irrigation line, but they do withstand standard household water pressures, so if you have the proper couplings to go from 1/2" drip line to your sprinklers they should work.

A:  I believe this pipe is specifically designed for the DIG system (or similar), as you can puncture holes in it to attach their other appurtenances. I think other pipe available would be more appropriate for a traditional under ground irrigation system.

A:  to my knowledge these fittings only work with Poly Drip Irrigation Tubing. If this is the type of line/tubing you are using then yes.

A:  Yes, I used it to repair a non-pvc sprinkler line. The pressure is much higher than a drip line but it has worked fine.

A:  It works to splice the underground 1/2" supply line.

A:  It will work but not very good not meant to have high pressure like a normal sprinkler

A:  This is a compression coupling for 1/2in poly tubing. Poly tubing irrigation is used above or below ground for drip irrigation in gardens. That said, you could also run 'sprinkler' style heads off a poly tubing-supplied watering system. It is not generally used for full-size lawn sprinklers - due to the restricted capacity of a 1/2in tube as opposed to the 'standard' use of 3/4in PVC pipe - which is far more durable than poly-tubing. That said, I have used above-ground poly-tubing fed full-size pop-up sprinklers to was a section of my backyard lawn that did not have installed PVC pipes. Though it works, you have to keep an eye on it to ensure the compression couplings haven't slipped and you have sliced or punched holes into the poly-tubing. So, in a pinch, yes you could use this for a sprinkler but it is not at all advised.
