Armstrong Fluid Technology 426401-003 Gasket
The Armstrong Fluid Technology 426401-003 Gasket is a high-precision 8" Nitrile Casing Gasket engineered specifically for heavy-duty commercial centrifugal pumps. Designed to facilitate a leak-proof seal between the pump casing and the cover, this component is essential for maintaining system pressure and preventing fluid loss in hydronic heating and cooling systems. This replacement pump gasket is compatible with a wide range of popular Armstrong Pump Series models, including the 4030, 4280, 4300, and 4380 series. With an outer diameter of 9 inches, an inner diameter of 8-1/4 inches, and a precise 1/16-inch thickness, this nitrile rubber gasket offers exceptional resistance to oils and various chemicals, ensuring long-term durability in demanding HVACR environments. Utilizing a genuine HVAC pump casing seal like the 426401-003 (often updated to the 8426401-003 part number) ensures exact dimensional fitment and chemical compatibility, reducing the risk of premature failure and costly system downtime during routine maintenance or full pump overhauls.
Key Benefits- Chemical Resistance: Constructed from high-grade Nitrile (NBR), providing superior resistance to oils, hydraulic fluids, and water-based solutions.
- Precision Fitment: Designed for an exact match on Armstrong 8-inch pumps, ensuring a reliable seal without the need for manual trimming or adjustment.
- Service Life: Engineered to withstand the thermal and mechanical stresses typical of commercial hydronic systems and high-pressure fluid transfer.
- System Efficiency: Prevents cavitation and pressure drops by ensuring an airtight and watertight casing connection.
Is the 426401-003 compatible with other pump brands?
While designed primarily for Armstrong Fluid Technology pumps, it may fit other brands with identical 8-inch casing dimensions; however, verify the 9" OD and 8-1/4" ID before installation.
What was the previous part number for this item?
This part often replaces older Armstrong Gasket iterations and is frequently cross-referenced with the updated manufacturer number 8426401-003.
Does this gasket require additional sealant during installation?
Standard nitrile pump gaskets are designed to seal under compression; always follow the pump manufacturer’s torque specifications to ensure a proper seat without over-tightening.
