Mechanical Pump Shaft Seals

Mechanical Pump Shaft Seals with Extended Spring

An extended spring on these seals accommodates variations in seal cavity length and pump misalignment.

Narrow-Profile Mechanical Pump
Shaft Seals with Extended Spring

With a smaller seal OD than standards seals, these seals have an extended spring that accommodates variations in seal cavity length.

Mechanical Pump Shaft Seals

These seals are commonly used in well, sump, and displacement pumps.

Mechanical Pump Shaft Seals with Compact Spring

Built for small circulation and dispensing pumps, these seals have short springs.

Expansion Joints

Expansion Joints with Flanged Ends

The flanged ends on these expansion joints rotate for easy bolt hole alignment during installation.

Expansion Joints with Butt-Weld Ends

These joints weld to unthreaded pipe or another butt-weld fitting for a leak-resistant permanent connection.

Expansion Joints with Sealing
Flanged Ends for Plastic Pipe

Expansion Joints with Sealing
Flanged Ends for Metal Pipe

Expansion Joints with Flanged Ends for High Vibration

These expansion joints have a double-bulb design for extra movement and vibration absorption.

High-Temperature All-Metal
Expansion Joints with Flanged Ends

These all-metal expansion joints can handle high temperatures up to 800° F.

Chemical-Resistant Expansion Joints with Flanged Ends

The PTFE body on these expansion joints has a super-smooth surface that stands up to corrosive chemicals.

Clamp-On Expansion Joints for Drain, Waste, and Vent

These joints are designed for vertical use in drain, waste, and vent systems.

Clamp-On Expansion Joints

Slip these joints over your pipe ends and tighten the band clamps for a secure hold.
