For use in waste water, boiler feed, and compressor pumps, these seals have an extra-long spring that accommodates variations in seal cavity length. They come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. The seat is comprised of the seat and the gasket.
Buna-N diaphragms and gaskets resist grease and a wide range of oils.
Viton® fluoroelastomer diaphragms and gaskets resist a wider range of chemicals than Buna-N.
EPDM diaphragms are more resistant to water and steam than Buna-N and Viton® fluoroelastomer, but aren’t as resistant to oils and chemicals.
Carbon washers are for use with clean liquids.
Silicon carbide washers have a hard surface that resists scratching, so they can be used with liquids that contain abrasives.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Designed to fit in housing bores that meet ANSI and DIN 24960, these seals have an extended spring that accommodates variations in seal cavity length. They're used in waste water, boiler feed, and compressor pumps. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. The seat is comprised of the seat and the gasket.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Built for high-speed circulation and dispensing pumps, these seals have a short spring that facilitates speeds up to 10,000 rpm. The spring-loaded design keeps the sealing surfaces in contact as the material wears. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. The seat is comprised of the seat and the gasket.
Buna-N diaphragms and gaskets resist grease and a wide range of oils.
Viton® fluoroelastomer diaphragms and gaskets resist a wider range of chemicals than Buna-N.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

These expansion joints have a double-bulb design for extra movement and vibration absorption. The flanged ends rotate for easy bolt hole alignment during installation. They mate with a same-size flat-surface Class 150 flange without the need for a gasket. Joints have a flexible body that is reinforced with nylon for added strength.

These joints reduce stress, vibration, and noise in piping systems by providing a point of flexibility to absorb movement. The flanged ends rotate for easy bolt hole alignment during installation. They mate with a same-size flat-surface Class 150 flange without the need for a gasket. Joints have a flexible body that is reinforced with nylon for added strength.

These joints reduce stress, vibration, and noise in plastic piping systems by providing a point of flexibility to absorb movement. Joints provide a tighter seal than other expansion joints because the flanges are molded into the body for a wide sealing surface. Each flange is supported by a zinc-plated steel plate. Flanges mate with a same-size flat-surface Class 150 flange without the need for a gasket.
