Part 441-151 Gasket Cushion is a compressible sealing and cushioning component designed for Hydra M and Hydra Pro Super series equipment. This gasket creates a leak-tight seal between mating surfaces while also providing vibration dampening and shock absorption. Replacing a worn, compressed, or damaged gasket cushion restores proper sealing, prevents fluid leaks, and reduces mechanical noise and vibration.

The 441-151 Gasket Cushion is a dual-function sealing component used in Hydra M and Hydra Pro Super series equipment. Manufactured from a compressible material, it provides a reliable barrier against fluid leakage while also absorbing vibration and shock between mating components such as pump mounts, motor bases, and fluid section interfaces.
Over time, exposure to chemicals, temperature cycling, and continuous compression can cause gasket cushions to harden, crack, or take a permanent set. A compromised gasket can lead to fluid leaks, increased noise and vibration, and eventual component misalignment. Replacing with this OEM-specification gasket cushion restores proper sealing and mechanical isolation.
| Fluid sealing | Prevents fluid escape between mating components |
|---|---|
| Vibration dampening | Absorbs mechanical vibration to reduce noise and wear |
| Shock absorption | Cushions against impact and sudden loads |
| Contamination barrier | Prevents external contaminants from entering sealed areas |
| Visible leaks | Fluid weeping or dripping from gasket interface |
|---|---|
| Compression set | Gasket is flattened and no longer springs back |
| Hardening / cracking | Material has become brittle or shows surface cracks |
| Excessive vibration | Increased noise or movement not previously present |
This gasket cushion is designed for the following models. Always verify your equipment's parts diagram to ensure correct fit and application.
| Brand / Model | Component |
|---|---|
| Hydra M | Gasket cushion |
| Hydra Pro Super | Gasket cushion |
When servicing gasket cushions, these associated components are often inspected or replaced at the same time.
Bolts, nuts, and washers should be inspected for corrosion or thread damage.
Inspect pump feet, motor mounts, and frames for cracks or wear.
Some applications may require additional sealant; check service manual.
