The oval packing, code EN14DB029052, is a specially shaped sealing element designed for the MAN L21/31 engine to ensure a tight fit between mating surfaces. Often used in valve housings or flanged joints, its oval geometry provides superior surface contact, enhancing its ability to prevent oil, fuel, or gas leaks under variable loads. Its resilience to heat, pressure, and chemical exposure makes it a key component in maintaining engine reliability and environmental safety.
