Non Metallic Clamps

Non Metallic Clamps are great for non metal sanitary hose connections

Rubber Fab’s Non Metallic sanitary hinge clamp is specifically designed for use on non metal to non metal connections!

  • Constructed of non metallic fiberglass reinforced nylon.
  • Accepts sanitary ferrules according to BS 4825, ISO 2852 and Tri-Clover® Standards.
  • Will not cause distortion in non metallic ferrules, as will stainless steel clamps during high operating temperatures and sterilization. Less weight than stainless steel clamps.
  • Use where reduction of weight and reduced thermal conductivity transfer is of importance.
  • Use on non metallic to non-metallic, non metallic to metallic and metallic to metallic sanitary mechanical joints.

Tests and Operating Capability

  • For use in GMP Manufacturing
  • Gamma stable to 25-40 kGy
  • Maximum irradiation dosage is 6 mega rads, this dosage is cumulative. Expect to see discoloration and the material to become brittle.
  • Autoclave Sterilize to 275°F (135°C) After autoclave clamp may need to be retorqued
  • Maximum recommended installation torque specification is 2nm.
  • Recommended working pressure, 150 p.s.i. @ 70°F
  • PTFE gaskets are not to be used in conjunction with the non metallic clamp. Acceptable elastomers are: Tuf-Flex®, Silicone, FKM, EPDM.
