4" Tri-Clamp Beaded Silicone Seal

Replacement silicone seal for 4" sanitary tri-clover fittings. 

4 inch tri-clover fittings are used on commercial brewing equipment, professional brewing equipment and high end home brewing units, particularly around large dup valves large distillation columns and high flow rate commercial equipment.

Each side of this silicone gasket is beaded, with both sides having a ridge around the entire circumference. This ensures the gasket stays seated between two tri-clover ferrules with the corresponding valleys and isn't dislodged or misaligned which can leakage or a seal to fail.

Silicone has several properties that make it ideal for brewing applications including:

- Resistance to crinkling and wrinkling
- Low chemical reactivity, silicone is extremely chemically resistant
- Thermal stability, Silicone can handle temperature ranges from -100 to 250℃
- Ability to form watertight seals
- Doesn't support microbiological growth
- Low toxicity
- Doesn't stick to substrates with the exception of glass
