Don't just use any old seals for your critical on-board systems. Keeping your coffee from dripping out of your thermos is nothing compared to the tough pressure, temperature and exacting tolerance requirements of aircraft engines and other components. K&S Enterprises specializes in specialty seals for hydraulic and pneumatic applications. Their seals are made from layered elastomer and woven fibers (such as silicone rubber and fiberglass cloth) which is then molded to the exact shape. These materials allow the seal to stretch over a part and then return to its original size so it provides a very secure fit. This family business was founded in 1971 by an engineer and machinist, and we're proud to count them among our elite manufacturers. Please call us if you have any questions about this or any other of our fine companies.
