Non Metallic Clamps

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.
