PACO Pump 99853453 O'Ring
For veteran technicians servicing industrial cooling towers and hydronic circulation loops, the PACO Pump 99853453 O'Ring is the mission-critical G4 model seal required for high-performance maintenance. Measuring with a 7.10" Inner Diameter (ID) and a 7.25" Outer Diameter (OD), this heavy-duty elastomeric pump seal is engineered to withstand the rigorous thermal and chemical demands typical of centrifugal pump applications. This part serves as the direct replacement for 91869180, ensuring zero-clearance 1:1 compatibility for older existing units. Originally designed for the PACO Type VL, VLS, and VLSC vertical in-line series, it functions as a primary volute O-ring or backplate O-ring depending on your pump's construction code (X0, X3, X4, or XA). By providing a hermetic seal against system pressure, this OEM-grade replacement part prevents fluid migration and protects the impeller assembly from external contaminants, maximizing the operational efficiency of your chiller or water circulation pump.
Key Benefits- Direct Compatibility: Engineered as the exact replacement for 91869180, eliminating the need for system modifications during seal replacement.
- High-Tolerance Sealing: Precision-molded 7.10ID x 7.25OD dimensions ensure a secure fit in the volute gasket groove for leak-proof performance.
- Industrial Durability: Rated for HVACR environments including cooling towers and commercial hot water systems.
- Simplified Maintenance: Essential component for pump seal kit overhauls, reducing labor time during scheduled preventative maintenance.
Is the 99853453 O-ring compatible with refrigerants?
Yes, this seal is designed for industrial HVAC system components, including chillers, and offers resistance to standard hydronic fluids and typical glycol-water mixtures.
Does this part replace the old 91869180 part number?
Correct. The 99853453 is the current manufacturer-designated replacement for the legacy 91869180 number and maintains identical technical specifications.
What pump models use this 7.25" OD seal?
It is most commonly utilized in PACO VL, VLS, and VLSC series centrifugal pumps with 7" and 12" frame sizes under specific construction codes like X0 and X3.
