Dylect® Pressure Washer Genuine Spare Part – Oil Seal 10×16×4 (Located in Pump Head – Plunger Seal Position) | NBR Rubber | Compatible Only with Flow Prime Model (Pack of 3)
The Dylect® Oil Seal 10×16×4 is a genuine Flow Prime Pressure Washer spare designed to prevent water leakage around the plunger during high-pressure reciprocation. Installed inside the pump head, it maintains proper sealing and ensures stable pressure delivery. Made from premium NBR rubber, it offers excellent elasticity, heat resistance, and long-lasting durability under repeated pump cycles.
A worn oil seal can cause leakage, pressure drop, and increased vibration. Service Note: Always replace all 3 seals together when servicing the pump. Using genuine Dylect seals ensures proper compression, protects pump components, and maintains long-term machine performance.
