The K203-375 is a Buna-N (Nitrile) U-Cup U-Cup Seal with a 1/8 inch inside diameter, a 2 inch outside diameter, and a height of 1/8 inch. This u-cup seal uses a U-shaped profile that system pressure forces outward, tightening the seal as pressure rises. This item is further identified as With 3/8 ID Hole IN Center.
This material stands up to propane and butane, water, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs.
Common environments for this compound include fluid power, agricultural equipment, and general industrial maintenance.
This item is sold individually under part number K203-375. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
