Gaskets - Tri-Clamp Gaskets - Black Buna (40MPU)
PNW Sanitary’s Black Buna (Buna-N) Tri-Clamp gaskets provide a durable, oil-resistant sealing solution for food, beverage, dairy, and general industrial processing lines. Designed for standard Tri-Clamp ferrules, these gaskets — modeled after profiles like 40MPU — offer strong compression, reliable sealing surfaces, and consistent performance in applications involving oils, fats, and non-aromatic hydrocarbons.
Buna-N gaskets are a practical choice for pump connections, valves, spool assemblies, and other process points where cost-effective durability is required. While not intended for high-temperature or aggressive chemical environments, they deliver excellent service life within their compatible operating range. Each gasket is precisely molded for accurate fitment, and product pages include material data and dimensional drawings to confirm suitability for your system.
All PNW Sanitary Black Buna Tri-Clamp gaskets are competitively priced and ready to ship, supporting routine maintenance and everyday sanitary processing needs.
