Pool Heater Manifold Hihitomorrow Pentair MasterTemp & StaRite–O-Rings

Description

Product Overview

The Hihitomorrow Pool Heater Manifold Kit is engineered as a precise, drop‑in replacement for the original manifolds used in Pentair MasterTemp (models 175, 200, 250, 300, 400) and Sta‑Rite Max‑e‑Therm (SR200, SR333, SR400) heating systems. Constructed from a high‑temperature resistant rubber‑plastic composite, the manifold offers superior durability against corrosion, chemical exposure, and thermal cycling. The kit includes a pre‑molded manifold, four premium O‑rings, and a roll of Teflon tape, providing everything needed to restore a leak‑free flow path without the need for additional components. Dimensions of the assembly are 8.86 x 5.51 x 5.91 inches and it weighs just 3.39 pounds, making handling and installation straightforward.

Usage

This manifold kit is intended for residential and light‑commercial pool and spa heating applications where the original manifold has become cracked, warped, or otherwise compromised. It is compatible with both the Pentair MasterTemp series and the Sta‑Rite Max‑e‑Therm series, covering a wide range of heater capacities from 175,000 BTU up to 400,000 BTU. The kit is ideal for DIY homeowners, pool service technicians, and professional installers who need a reliable, OEM‑compatible solution that eliminates leaks and restores optimal heat transfer. The replacement process assumes the existing backing plate, sensors, and drain valve remain undamaged, allowing the new manifold to be installed with minimal disassembly.
