Description
BUNA-N Tri-Clamp Gaskets
Buna-N Tri-Clamp gaskets are the preferred choice of material when using a closed loop, closed column, or open blast extraction when butane or propane are used as the extraction solvent.
Buna-N Gaskets offer a lower temperature rating and have better physical properties than Viton gaskets; the best part is that they cost less than Viton and provide the same chemical resistance to butane and propane.
Note: BUNA-N is not recommended for use with certain alcohols
Key Features:
- Lower temperature range
- Lower costs
- Better compressibility and springiness
- Excellent resistance to butane and propane
- Better tear resistance
- Better abrasion resistance.
- FDA CFR 177.2600 – Rubber and Rubber-Like Material for Repeated Use/Contact with Food.
- FDA CFR 177.1550 – Fluorocarbon Resins for Repeated Use/Contact With Food, Dairy & Pharmaceutical Products.
