Sanitary Tri-Clamp (Ferrule) Gaskets — Moulded to Your Clamp Standard
Tri-clamp gaskets that seat between two ferrules on hygienic process pipework and reseal every time the line is opened for cleaning. Moulded to the ferrule sizes of DIN 32676, ISO 2852 or ASME BPE, in EPDM, silicone, NBR or FKM. Dairy screw-coupling seals are made too. Made at our plant in Vilholi, Nashik.

Key facts
A sanitary tri-clamp gasket is the moulded rubber ring that seats between two ferrules on hygienic process pipework and reseals each time the line is opened for cleaning. Margo Rubber moulds tri-clamp gaskets to DIN 32676, ISO 2852 or ASME BPE ferrule sizes in Vilholi, Nashik.
Tri-clamp sizes do not all match across DIN 32676, ISO 2852 and ASME BPE, so a gasket made for one can sit proud or short in another. The drawing should name the standard the ferrules were made to. Margo Rubber moulds them in EPDM to +140 °C or silicone to +200 °C.

Rubber Compound Options
Select the compound best suited to your operating environment and application requirements.
| Rank | Compound | Temperature | Choose it when |
|---|---|---|---|
| Default | EPDM | −40 to +140 °C | Hot water, steam and CIP. The usual pick for dairy and beverage lines. |
| Leave EPDM if… | the product is fatty or oily | — | Specify NBR (−30/+120 °C). |
| Leave EPDM if… | the line runs dry heat | — | Specify silicone (−60/+200 °C). |
| Leave EPDM if… | the line runs hot acid cleaners or hot oil | — | Specify FKM (−20/+250 °C); not for steam or hot caustic. |
| Also available | AEM (−40 to +160 °C) · Neoprene (CR) (−40 to +120 °C) · SBR (−30 to +100 °C) · Natural rubber (−20 to +90 °C) | See each compound | The rows above are about which one your part needs. |

Key advantages
Why Specifiers Choose Margo
Name the standard
DIN 32676, ISO 2852 and ASME BPE do not match in every size. A gasket cut for one can sit proud or short in another.
Chosen for the wash
Tell us the CIP chemistry and temperature. The wash is often harder on a clamp gasket than the product is.
Moulded, not punched
The groove bead is moulded in, so the gasket locates in the ferrule every time it is refitted.
Tested in-house
Hardness, tensile and compression set in our own lab, with the report in every shipment.

Manufacturing process
From Compound to Certification
Material compounding
Polymer, fillers and cure system mixed in-house for the medium and temperature on your drawing. Cure is checked on our ODR rheometer.
Tool design
Moulds designed and made for your part and held as a controlled record. When a mould already exists, first samples take 48–72 hours.
Moulding
Compression moulded, with the cavity count set by your volume.
Trimming
Flash trimmed to the edge condition on the drawing.
Inspection
Dimensions against the drawing, hardness and batch sampling. Results go into the shipment documents.
Export packing
Packed by part number with labels that match the inspection sheet. ISPM-15 treated pallets where timber is used.
Quality assurance
Tested in Our Own Lab, Documented in Every Shipment
Every consignment ships with a material test report, a dimensional inspection sheet and a certificate of conformance. Hardness, tensile and elongation (ASTM D412), density, compression set (ASTM D395 Method B), heat ageing, ozone resistance, fluid swell and low-temperature tests run in our own lab, and cure curves run on our own ODR rheometer. PPAP is available on request. RoHS declarations are issued for all compounds.

Technical & Commercial Questions
Answers to the most common questions from engineering teams and procurement managers worldwide.
What is the minimum order for tri-clamp gaskets?
There is no fixed number. The minimum is set by part size and tooling, and we quote it with the part. Send the drawing and your annual volume and you get both figures in one reply. Prototype and first-article lots sit outside the minimum.
Do you stock standard tri-clamp sizes?
No stock range. We mould each size to the standard and drawing you name.
Are your compounds suitable for food contact?
We hold no food-contact certificate for any compound, so food-contact compliance stays with your equipment approval. Tell us the product, temperature and cleaning cycle and we choose the compound for that duty.
Do you send test reports with each shipment?
Yes, with every consignment: material test report, dimensional inspection sheet and certificate of conformance. Hardness, tensile to ASTM D412 and compression set to ASTM D395 Method B are tested in-house.
What are your payment and delivery terms for export orders?
TT and LC, agreed per order. Ex-works Nashik or FOB Nhava Sheva. The commercial invoice, packing list and certificate of origin (Nashik Chamber of Commerce) travel with every consignment.
