The MYA‑type dual‑purpose seal is a versatile hydraulic sealing component designed for both piston and piston rod positions within hydraulic cylinders. Formulated from high‑performance polyurethane elastomer, this seal delivers outstanding wear resistance, extrusion resistance and great compatibility with most standard hydraulic fluids, performing reliably under repeated reciprocating movements.
Benefiting from optimized cross‑section design, the MYA‑type seal creates uniform radial contact pressure. It prevents medium leakage efficiently and tolerates minor eccentricity and installation deviations. Thanks to its universal structural profile, it can be applied on either piston or rod grooves, helping reduce spare‑part types and simplify inventory management for manufacturers and maintenance workshops. Installation is quick and convenient without requiring special assembly tools.
It works stably across a wide temperature scope and fits medium‑pressure hydraulic systems. Widely used in construction machinery, agricultural equipment, material‑handling machines and general industrial hydraulic cylinders, MYA‑type dual‑purpose seal offers flexible sealing solutions. Proper groove dimension control and qualified surface roughness will significantly extend service life. As a cost‑effective multi‑functional sealing part, it lowers leakage failure and improves overall hydraulic system stability.
