Terry Clamp Power Grip

Our "Powergrip" range of worm drive hose clips is produced to the exacting requirements of BS5315:1991. This standard, met by only a few manufacturers, ensures consistent performances, combining ease of assembly with secure sealing.
Low free torque! Powergrip hose clips have low free torque to allow the screw to move freely during assembly under a torque of less than 1.5 Nm.
High tightening torque! The British Standard also requires clamps to be capable of withstanding high tightening torques. This ensures that "Powergrip" clips may be safely applied without fear of damage to hoses through over-tightening.
Hydraulic pressure test - BS5315:1991 also specifies hydraulic pressure tests to which "Powergrip" are subjected during normal production testing. Details available on request.
Reliable.
Our clamps are designed to have a clamping force reserve and not break. They will reliably continue to develop a sealing force around the hose when tightened 360° around the joint.
Clamping force meter.
If you wish to compare the clamping force of different products, we can help you on site with our portable measuring equipment. Once the clamping force has been determined, a suitable level of corrosion protection can be selected within our material range.
Product development.
We continuously test systems of hoses, pipe ends, clamps and couplings at our Technical Centre, in order to develop new products and to improve our existing products.
Technical Centre in Anderstorp, Sweden.
Mechanical efficiency is one of our test parameters. An increase of tightening torque does not always mean an increase in clamping force! Here the clamp design and lubrication play vital roles. Our Technical Centre has state-of-the-art equipment for testing of pressure, vibration and temperature variations - essential parameters which over time will affect a hose or pipe connection. Many customers have during recent years asked us to perform tests and give technical advice concerning their specific applications.
In industry, the choice of clamp is important. Therefore, we have developed a meter that measures the exact clamping force at eight points, directly after installation and over extended periods of time. Tests have shown that our products achieve high clamping forces before breaking and thus ensure that the customer has a clamping force reserve in the clamp to avoid blow-off or leakage over time.
