Pentair In/Out Bushing, 2-Inch ID | 070544

Genuine Pentair inlet and outlet connection bushing for select MiniMax Plus pool and spa heater assemblies.

What is Pentair part 070544?

Pentair 070544 is an inlet and outlet bushing used within the water-header and plumbing connection assembly on compatible Pentair MiniMax Plus pool and spa heaters. Two bushings are typically used per heater, with one positioned at the water inlet and one at the water outlet.

Product Overview

The Pentair 070544 In/Out Bushing is a genuine Pentair heater plumbing component designed to fit between the heater’s water-header assembly and its inlet or outlet connection. It helps position and support the connection where pool water enters or exits the heater.

Correct identification is important because Pentair heater assemblies may use several similar-looking bushings, sleeves, gaskets, adapters, and flange components. Always match the complete heater model and original manufacturer part number before installation.

What This Bushing Does

The inlet and outlet bushing is installed within the heater’s water-connection assembly. It supports the interface between the heater header and the surrounding plumbing components where circulated pool or spa water enters and exits the heat exchanger.

A worn, cracked, distorted, or incorrectly sized bushing may prevent the surrounding components from seating correctly. The complete connection should be inspected whenever leakage, movement, corrosion, or damage is found near the heater inlet or outlet.

Installation and Inspection Guidance
  1. Turn off electrical power and gas to the heater.
  2. Shut down the circulation pump and relieve all system pressure.
  3. Allow the heater and surrounding plumbing to cool completely.
  4. Confirm the heater model and original Pentair part number.
  5. Inspect the header, flange, sleeve, seals, adapters, and plumbing connections for damage.
  6. Replace damaged sealing or connection components as required.
  7. Pressure-test the repaired connection before returning the heater to service.

Pool-heater repairs should be completed by a qualified service professional familiar with gas-fired equipment, pressurized plumbing, and the applicable Pentair service documentation.

Part Identification

Use the following information when identifying this component:

  • Pentair part number: 070544
  • Common description: In/Out Bushing
  • Nominal inside diameter: 2 inches
  • Assembly area: Heater water inlet and outlet
  • Typical installed quantity: Two

Do not confuse this bushing with the separate rubber sleeve, quick-flange kit, flow-valve gasket, bulkhead adapter, or header components used in the same general area of the heater.

Frequently Asked Questions

What is the Pentair 070544 used for?

It is used at the inlet and outlet water connections on compatible Pentair pool and spa heater assemblies.

What is the inside diameter?

The listed inside diameter is 2 inches.

How many bushings does one heater use?

Pentair’s parts documentation identifies a quantity of two, allowing one bushing for the inlet and one for the outlet.

Does this fit every Pentair heater?

No. Compatibility depends on the heater family, model size, production generation, header assembly, and existing plumbing configuration.

Is this the same as the rubber inlet and outlet sleeve?

No. Pentair identifies the rubber inlet and outlet sleeve as a separate component. Confirm the original part number before replacing either item.

Can this part stop a heater connection from leaking?

It may be one component within the connection, but leaks can also result from damaged sleeves, seals, flanges, adapters, headers, loose plumbing, or cracked components. Inspect the complete assembly before determining the repair.

Confirm Your Heater Before Installation

Match the complete Pentair heater model, heater size, existing inlet and outlet assembly, connection dimensions, and original part number 070544. Similar-looking heater bushings and sleeves are not automatically interchangeable.
