  • The SMS Aseptic fitting is a patented modified version of the SMS standard union, designed to accept an ‘L’ section joint ring and give a true crevice free bore.
  • On assembly, the nut is tightened until metal to metal contact is made between the outer rim of the liner and male part.
  • This gives a present compression on the seal, eliminating the possibility of overtightening and prolonging joint life.
  • The liners are of the long type with a shoulder which is dimensioned and tolerance to locate inside the nut to give perfect concentric alignment on assembly.
