Product details

The Pentair 77707-0233 is the tube sheet coil assembly kit for Pentair MasterTemp and Sta-Rite Max-E-Therm 300K BTU heaters, models 300NA and 300LP built before January 12, 2009.

What it does

The tube sheet assembly is the heat exchanger core of the heater. On these MasterTemp and Max-E-Therm models the tubes have a generally round, coiled shape instead of the straight, flat layout used by most other heaters. The 300K BTU tube sheet contains 6 coiled tubes. The plate at the end of the tubes measures 5-1/2 in. wide by 8-1/2 in. tall, the approximate width side to side is 13 in., and the approximate length from the end of the plate to the opposite end of the coil is 15 in.

Fit and compatibility

The kit is used in models 460734, 460735, SR333NA and SR333LP, and it fits 300NA and 300LP heaters built before 1-12-09. Confirm the model and the build date on your heater before ordering. It is listed under the Sta-Rite SR333 designation as well.

What is included

The kit comes with a clamp, an O-ring kit of 12 (part number 77707-0119) and a tube of high temp RTV silicone, so the main sealing parts are in the box with the coil assembly.
