Multiquip 577009 Drain Plug Gasket

The Multiquip 577009 Drain Plug Gasket is a genuine OEM component designed for SP, PS, and CS series pavement saws and flat saws. This gasket delivers a positive, leak-free seal at the drain plug, protecting the engine or gearbox oil from contamination and loss during operation and routine fluid changes. Confirmed fitment spans a wide range of Multiquip pavement saw models including the SP303516, SP303530, SP605716, SP605730, PS403016, PS403030, PS706016, PS706036, CS403016, CS403030, CS706016, and CS706036, among others. As a genuine Multiquip OEM part, 577009 is manufactured to the same specification as the original component installed at the factory, so it installs directly without modification.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to exact material and compression specifications, ensuring the gasket seats and seals correctly at the drain plug interface every time.
• Direct Drop-In Installation — Engineered to match the original drain plug thread seat geometry on SP, PS, and CS series saws, so replacement is straightforward during any scheduled fluid service.
• Broad Saw Series Compatibility — Fits SP, PS, and CS pavement and flat saw models across multiple blade and engine configurations, making it a practical single-part solution for mixed fleets.
• Prevents Oil Loss and Contamination — A failed or deteriorated drain plug gasket allows oil to seep past the plug, leading to low oil levels, accelerated wear, and potential engine or gearbox damage.
• Fluid System Confidence — Using the correct OEM gasket on a fuel or oil drain plug is a straightforward way to avoid slow leaks that can go unnoticed between inspections.

The drain plug gasket forms the sealing barrier between the drain plug and the oil pan or gearbox housing, preventing oil from escaping around the threads during operation. When this gasket becomes compressed, cracked, or loses its elasticity over time, even a fully tightened plug can allow a slow seep that compromises oil level and leads to accelerated internal wear. Replacing the drain plug gasket at every oil change interval is a low-cost step that protects the much larger investment of the engine or gearbox it serves.
