DESCRIPTION

Mechanical Seal 1000 — Type 6 (5/8″) | PS-1000

Equal to industry standard 1000 / PS-1000.
Direct-fit Type 6 single-spring seal for pool/spa and small-pump applications—built with molded carbon/ceramic faces and Buna-N elastomers for reliable everyday service.

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

Fits: Pentair IntelliFlo®, WhisperFlo® and Ultra-Flo (071734S), the Polaris PB4-60 booster pump, Jandy, Sta-Rite and American Products Eagle and Maxim pool pumps, plus Astral Pool, Doughboy, Gecko and Acura spa systems. Pentair IntelliFloXF takes the PS-201; the Polaris PB4-60Q takes the PS-3890.

Same seal, same size, same fit — what changes is the material and how it’s built. All five seals below are the PS-1000 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
1000	Molded carbon face, ceramic seat, Nitrile rubber	Normal chlorine, normal temperature, clear water. The standard build for a home pool or spa.
1000cv	Molded carbon face, ceramic seat, Viton rubber	Saltwater or higher chlorine, and warmer water. Viton holds up where standard Nitrile hardens and cracks.
961	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.
3865	Machined premium carbon face, ceramic seat, Viton rubber	High chlorine and hot water — heated spas, therapy pools, heavy commercial duty.
1000cvss	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 6
Our Type 6 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 6 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.
