Hygienic Fittings & Sanitary Gaskets

ATC offer a wide range of hygienic fittings and tubing. These hygienic fittings are used in the food, dairy, beverage, medical and pharmaceutical industries.

Hygienic Fittings and Sanitary Gaskets Materials

Sanitary gaskets are available in a range of materials including EPDM, Viton®, Buna-N, and Silicone and Fluoropolymer (PTFE). All compounds are FDA compliant. They allow for pipe and tubing connections to be made in a sanitary fashion that is designed to be cleaned in place (CIP) but is easily broken down for further cleaning, inspection and repair.

Hygienic fittings are corrosion resistant and they limit entrapment areas where bacteria could form or propagate, thereby providing fittings that are hygienic and are ideal for use in controlled environments.

What types of hygienic fittings and sanitary gaskets are available?

Hygienic Fittings provided by ATC include but are not limited to:

  • Tri Clamp Ferrules
  • Tri Clamp Clamps
  • Tri Clamp Blanks
  • Tri Clamp Gaskets
    • Screen & Sock Gaskets with various mesh sizes
    • Source gaskets
    • Gauge gaskets
    • Envelope gaskets with either EPDM or Viton filler
    • Metal Detectable gaskets

The gaskets listed above can be offered in a range of colours and materials including EPDM, PTFE, Silicone (Platinum & Peroxide Cured), Viton & Polysteel (PTFE mixed with 316 stainless steel).  The sanitary ferrules and blanks are available in stainless steel grade 316 and clamps in grade 304.

USP Class VI and FDA Certification available

ADI/BSE/TSE free certification also available

High Purity pipework and Fittings according to ASME BPE

High Purity Platinum cured silicone hose

In addition to the above ATC can also offer the following unions:






Introducing Sanifluor

It’s well known that CIP (cleaning in place) utilizes chemicals that can attack the majority of elastomeric seals. SIP (sterilization in place) employs superheated steam which can even have an even greater detrimental effect. The traditional elastomeric sealing materials (Silicone Rubber, EPDM, Fluoroelastomer (Viton®) and Perfluoroelastomer (Kalrez) frequently fail prematurely when exposed to combinations of chemicals, high temperatures and steam/water. Teflon® falls short on its “sealability” characteristics. That’s because Teflon is a plastic and readily changes shape when compressed. When used as a sanitary gasket, it will typically work well on its first usage but after that it will likely cause some leakage.  A failing/failed gasket or O-Ring will likely result in leakage, leaching and the risk of contamination.  A common fix for leaking gaskets is continued tightening, but this is not a long-term solution.

  • Why use Sanifluor?

Sanifluor® 1000 elastomer was specifically formulated to overcome the vulnerabilities of Silicone Rubber, EPDM and Viton in these harsh environments. O-Rings, Gaskets and Seals produced from Sanifluor® 1000 have excellent chemical, heat and steam resistance. Their superior performance under harsh conditions makes them ideal for pharmaceutical, medical, biotechnology, food, beverage and cosmetic manufacturers who use steam or caustic chemicals in their sterilization processes. Sanifluor 1000 produces low TOC’s and metal extractables, and is both FDA and USP Class VI Compliant. It also complies with 3-A Sanitary Standard for multiple-use rubber materials. Sanifluor is recommended for service in processes that operate up to 450°F / 230°C.

Sanifluor® provides excellent performance in SIP (steam in place), CIP (clean in place) and WFI (water for injection) applications.  Sanifluor® 1000 is available in all sanitary gasket sizes for Tri-Clover,® Tri-Clamp®, fittings, AS-568A O-Ring sizes and custom shapes.  If you are looking for a solution to premature seal/gasket failure in CIP, SIP or similar aggressive environments, it is worth considering the use of Sanifluor®1000 gaskets and O-Rings.
