    Replaces types such as Type 16, G, A, 6, AV, 2100

    • Please note: CAR/CER/NIT. Our carbon face is precision-machined from solid, resin-impregnated carbon stock—not a molded plastic/phenolic face like ps-702 or other equals. The same premium carbon face is used in CAR/CER/VIT, which substitutes Viton elastomers for higher chemical and temperature resistance

  • 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 carbon face (never plastic) — 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
