  • DESCRIPTION

    Mechanical Seal 201CVSS — Type 166 / T-16 (3/4″) | PS-201V-SC-SC

    Equal to industry standard 201CVSS / PS-201V-SC-SC.
    Direct-fit Type 166 / T-16 single-spring seal for pool/spa and small-pump applications—engineered with hard faces and chemical-resistant elastomers for longer service life.

    At-a-glance spec: 3/4″ shaft • 1.375″ × 0.406″ cup seat • Silicon Carbide / Silicon Carbide faces • Viton/FKM elastomers

    Fits: Hayward Super Pump®, Super Pump II, Super Pump VS and the original Max-Flo (SPX1600Z2), Pentair IntelliFloXF® and SuperFlo® VST (17351-0101S), Sta-Rite Dura-Glas® II, Max-E-Glas™ II, Max-E-Pro® and Dyna-Pro®, plus Pac-Fab, American Products, Purex, Swimquip and Jacuzzi pool and spa pumps. The standard Pentair IntelliFlo takes the PS-1000; Pentair SuperFlo / SuperFlo VS and Hayward Max-Flo II take the PS-200.

    Same seal, same size, same fit — what changes is the material and how it’s built. All five seals below are the PS-201 for a 3/4″ shaft, and all five fit the same pumps. They differ in two ways. The build: a molded carbon face or a premium carbon face machined from solid stock. The materials: a ceramic or silicon carbide seat, and Nitrile or Viton rubber. Pick the one that suits your water.

    Seal Material Best For This Water
    201c Molded carbon face, ceramic seat, Nitrile rubber Normal chlorine, normal temperature, clear water. The standard build for a home pool or spa.
    201cv Molded carbon face, ceramic seat, Viton rubber Saltwater or higher chlorine, and warmer water. Viton holds up where standard Nitrile hardens and cracks.
    851 Machined premium carbon face, ceramic seat, Nitrile rubber Saltwater pools with a chlorine generator, commercial pools, or any pump that runs most of the day.
    3868 Machined premium carbon face, ceramic seat, Viton rubber High chlorine and hot water — heated spas, therapy pools, heavy commercial duty.
    201cvss Silicon carbide face and seat, Viton rubber Sandy, dusty or gritty water, or any pump where seals keep failing early. The hardest faces we offer.

  • PHYSICAL PROPERTIES

    Seal House Type 166
    Our Type 166 configuration combines the best design elements we’ve refined over the years to deliver superior reliability and performance.

    Key advantages include:

    • Crimped rotary face with positive drive — securely held in place to prevent dislodgement during installation.

    • Full metal retainer with positive drive — ensures strength and long-term durability.

    • Full rubber bellows construction — provides complete sealing along both the shaft and face, rather than relying on a small O-ring or partial gasket.

    • Molded/machined carbon face (never plastic) with upgrade options — delivers extended service life.

    Compatibility & upgrade:

    The Type 166 is designed to replace most small seal types commonly used in pool and spa applications, including Type 16, G, A, 6, AV, 2100, and more. Even in its basic form, this seal is a significant upgrade over standard “pool” seals typically available on the market.
