I hope you managed to get a hold of one of us by now, but if not, I am sorry that we didn't get in touch with you sooner.
A good butt fusion joint is the most reliable, least expensive, and longest life joint and should be used everywhere possible. In those cases where you can’t, I would recommend the Hymax Grip® mechanical fitting or EF.
It is easier and more productive to fuse above ground and then lower the line in the ditch. In cases where you need to fuse in the ditch, the Pit Bull® is available, or the carriage from the 4 wheel cart or TracStar® can be removed and operated in the ditch.
You mentioned that the “MHs are stubbed out”, so I assume that the outlets are fused to the MH. (Note: If the outlets are only clamped on, we offer Sidewall fusion machines to make that joint leak free.) If the stub is long enough to clamp with one fixed clamp and allow for face off, then the pipe could be fused directly to the stub, at least at one end. Typically the last joint between MH’s is done with a mechanical fitting or EF.
The line of Hymax fittings is manufactured by Krausz of Israel and is a member of the PE Alliance.
Hope that this is of some help. Please contact us via our Tech Support phone line (918)831-9224 anytime we can be of service.
