Please contact customer service if you need oneO-rings are the most commonly used oil seals in hydraulic cylinders. They are a typical type of lip seal and provide excellent sealing performance whether used on pistons or piston rods.In low-pressure conditions, a U-ring relies solely on the elastic deformation of its lip to create a seal. As pressure increases, the elastic deformation of the lip increases, leading to greater tensile, compressive, and bending stresses. Consequently, the radial pressure of the U-ring automatically increases, and the length of its contact with the sealing surface continuously increases until the entire axial length of the U-ring comes into contact with the sealing surface, thereby ensuring good sealing performance under high-pressure conditions.UN is a universal standard for threaded connections, characterized by symmetrical flange-like lips on both sides. It can withstand working pressures ranging from 21 MPa to 35 MPa and is temperature-resistant from -35°C to 100°C℃Left and right, made of M-90 material.
