DESCRIPTION

Mechanical Seal 200 — Type 166 (5/8″) | PS-200

Equal to industry standard 200 / PS-200.
Direct-fit Type 166 single-spring seal for pool/spa and small-pump applications—built with molded carbon / ceramic faces and Buna-N elastomers for dependable everyday service.

At-a-glance specs: 5/8″ shaft • 1.25″ × 0.406″ cup seat • Carbon/Ceramic faces • Buna-N elastomers

Fits: Hayward Max-Flo II® and Max-Flo VS (SPX1250XZ2), Pentair / Pac-Fab Challenger®, Dynamo®, Dynatron® and Pinnacle®, Sta-Rite Dura-Glas® and Max-E-Glas® Series PE, PEA, P2R and P2RA, plus Speck, Waterway, Jacuzzi, Astral Pool and Doughboy pool and spa pumps. The original Hayward Max-Flo (SP2800X) and Dura-Glas II / Max-E-Glas II take the PS-201; pre-1998 Dura-Glas takes the PS-100.

Same seal, same size, same fit — what changes is the material and how it’s built. All five seals below are the PS-200 for a 5/8″ 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
200c	Molded carbon face, ceramic seat, Nitrile rubber	Normal chlorine, normal temperature, clear water. The standard build for a home pool or spa.
200cv	Molded carbon face, ceramic seat, Viton rubber	Saltwater or higher chlorine, and warmer water. Viton holds up where standard Nitrile hardens and cracks.
516	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.
3867	Machined premium carbon face, ceramic seat, Viton rubber	High chlorine and hot water — heated spas, therapy pools, heavy commercial duty.
200cvss	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 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.
