    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

    Why choose 201CVSS:

    • SiC/SiC faces provide excellent wear and heat resistance

    • Viton handles higher chlorine, heat, and chemicals better than Buna

    • T-16 footprint for quick, drop-in replacement

  • 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.
