METAL HOSE
Metal hose is a length of tubing made flexible by means of convolutions, so that it may
be readily bent, but remain liquid and gas tight.

Pressure
• Noise control
• Vibration absorption
• Compensates for misalignment
of pipes or equipment

4. PUMP CONNECTORS
Pump connectors are designed to
meet these needs in a piping system:
• System forces
• Dampen noise
• Compensation
• Absorb vibration
• Accommodate misalignment
Pump connectors CAN NOT be used
for thermal expansion applications.

PRODUCT LINE TRAINING
Model Pipe Guides
And Slides
Sizes 1/2” - 24”
Features
• Designed to facilitate
the thermal expansion
of a pipeline so that the
axial movement is
properly directed to
the expansion joint
• Prevent buckling
or squirming of the
piping system
• Proper guiding and
anchoring are essential
to the proper function
of expansion joints
