Type SB1
Single, Heavy-duty Cartridge Seals
The Safeseal Type SB1 is a single-cartridge seal for use with clean fluids and lubricants. It is versatile and easy to install and maintain. Although the design of the seal is simple, it contains advanced technical features, such as patented seal face holders and elastic mating ring. Seal faces are installed using a patented heat shrink process ensuring correct, distortion-free face alignment at all recommended temperatures. The Type SB1 seal is applicable for a wide range of duties such as water, oil, solvents and pulp.
Several variant of the design available for different services:
Type SB1 — Single, balanced cartridge seal, metric units (DIN)
Type SB1A — Single, balanced cartridge seal, imperial units (ANSI)
Type SB1B — Single, balanced cartridge seal, imperial units for big box bore pumps. The Type SB1B flange is designed to fit bigger stuffing box diameters.
Type SB1S — Single, balanced cartridge seal, imperial or metric units. Metric versions of SB1A seals are also called SB1S.

- California Residents: PROPOSITION 65 WARNING
- The springs are located in the stationary body of the seal, reducing risk of the springs becoming clogged.
- PTFE slot rings replace the traditional O-rings in places where they are exposed to the product, preventing sticking.
- Protected faces, the seal face carriers are driven by machined fits, preventing metal stress from distorting the face.
