Product details

The Pentair 77707-0120 is the manifold o-ring kit for the burner system used on Max-E-Therm and MasterTemp heaters. It is the genuine Pentair part.

What is in the kit

The o-rings for the manifold, the tube and the coil, supplied together as one kit. Those are the seals disturbed whenever the burner system is opened up for service.

Why replace them as a set

Old o-rings take a set, harden and stop sealing once they have been compressed and then released. Since almost all of the work is in opening the heater, changing every seal at once is the sensible way to do it rather than reusing two and coming back for them later.
