Autotrol Magnum IT (298) 3023674 Magnum 2" BSP adapter kit

This is the 2" BSP adapter kit for the Autotrol Magnum IT (298) commercial control valve, part number 3023674, used to connect the valve's large-bore inlet and outlet to 2" BSP pipework on commercial water treatment installations. It includes the fittings and seals needed to make a watertight connection between the valve body and site pipework. WrekinWater supplies this kit to installers plumbing in new Magnum IT valves or replacing damaged or missing adapters on an existing commercial softener or filtration system.

Technical specifications

Symptoms that mean you need this part

• The existing 2" adapter is cracked, split or leaking at the pipework joint
• You're plumbing in a new or replacement Magnum IT valve and need the correct 2" BSP connection kit
• Adapter seals have perished or won't hold pressure even after retightening
• Mismatched or improvised fittings are being used in place of the correct adapter, causing recurring leaks

Why it fails / why it matters

The Magnum IT (298) is a high-flow commercial valve designed for large-diameter pipework, and it connects to site plumbing through a dedicated 2" BSP adapter kit rather than a standard domestic fitting, since the bore and seal design have to handle the higher flow rates these systems are built for. Over time the adapter seals can perish or the adapter body itself can be damaged during installation or servicing, and because this is a specialist commercial fitting, a mismatched or improvised replacement is a common cause of leaks that a genuine-spec kit avoids. Fitting the correct 3023674 kit ensures the valve connection is rated for the flow and pressure the Magnum IT is designed to handle.

How to fit it

1. Isolate the system at the bypass and fully depressurise the pipework before disconnecting the existing adapter
2. Remove the old adapter from the valve inlet or outlet port and inspect the port and seal face for damage
3. Confirm the replacement kit (3023674) matches your Magnum IT valve configuration before fitting
4. Fit the new seals supplied in the kit to the adapter, lubricating lightly to ease assembly
5. Thread the adapter into the valve port and connect to the 2" BSP site pipework, tightening to a firm hand-tight plus appropriate turn without over-torquing the plastic body
6. Restore the water supply gradually and check the joint thoroughly for leaks under full pressure before returning the system to service
