The Techné clamp seal is an aseptic seal exclusively used in clamp (or tri-clamp) fittings. Depending on the country and the field of application, there are several dimensional standards:
Clamp seal DIN 32676
Clamp seal ISO 1127
Clamp seal SMS ISO 2852
Clamp seal BS OD/BS4825-3
A complete fitting is composed of two ferrules, a clamp for assembly and a seal for clamp fitting. This composition allows a simple and fast disassembly and reassembly of the set.
Aseptic seals are compatible with ferrules to DIN 32676.
Profiles
Four profiles of triclover clamp seals are available:
Clamp seal type A (flanged)
Clamp seal type B (not flanged)
Mini clamp seal
Micro clamp seal
Namely:
For a ferrule outer diameter of 25 mm, the profile is a micro clamp or µ clamp.
For a ferrule outer diameter of 34 mm, the clamp A or B is called mini clamp.
From a ferrule outer diameter of 50.5 mm, the seal is called clamp.
Main applications
The clamp seal is intended to ensure the sealing in the connection of several elements of piping. The main consumers of clamp seals are the food, chemical, pharmaceutical and medical industries.

Materials and approvals
Human health is a central concern for the food, chemical and pharmaceutical industries in the manufacture and quality control of products for human consumption. Consequently, these fields require materials that meet their specifications in order to limit the impact of materials on their environment.
