March 0809-0165-1000 Silicone Pump Housing O-Ring

The March 0809-0165-1000 is a silicone rubber replacement O-ring used in compatible March Series 809 brass and stainless steel magnetic drive pumps. This seal is installed between wet end housing surfaces to support fluid containment.

Manufacturer parts documentation distinguishes this O-ring from the silicone seal used in plastic housing configurations, making the housing material an important selection factor.

Key Features and Benefits

• Silicone Rubber Construction: Original manufacturer-specified sealing material.
• Static Housing Seal: Helps prevent leakage at the wet end housing joint.
• Metal Housing Applications: Listed for compatible brass and stainless steel Series 809 pumps.
• Maintenance Replacement: Supports repair and reassembly of the original wet end.

Applications and Compatibility

Used in compatible March Series 809 metal housing pump assemblies. Confirm the complete model and sealing material before ordering because plastic housing versions may require a different O-ring.

Installation and Ordering Guidance

Remove the old seal and inspect the housing groove for contamination or damage. Install the replacement without twisting or pinching it and confirm fluid compatibility. Order using 0809-0165-1000.
