Dylect® Pressure Washer Genuine Spare Part – O-Ring 5.5×2 (Located in Pump Head – Small Port Seal Position) | NBR Rubber | Compatible Only with Flow Prime Model (Pack of 3)
The Dylect® O-Ring 5.5×2 is a genuine sealing component designed for the small internal passages of the Flow Prime Pressure Washer pump head. Made from high-quality NBR rubber, it ensures a tight, leak-free seal under high-pressure operation. Its elasticity and durability make it ideal for continuous compression cycles inside the pump.
Worn or hardened O-rings can cause internal leakage, pressure instability, or reduced washer performance. Service Note: Replace all three O-rings (Pack of 3) together during servicing to maintain balanced sealing and optimal pump performance. Genuine Dylect seals ensure long-term reliability and consistent pressure delivery.
