Multiquip 1522133140 Oil Filter Plug

The Multiquip 1522133140 Oil Filter Plug is a genuine OEM component designed for the BLW-400SSW welder. As a direct Multiquip OEM part, it is manufactured to the exact specifications required for proper sealing at the oil filter port, ensuring no compromise in oil system integrity. This plug is the correct replacement for BLW-400SSW units and installs directly into the factory-threaded port with no adaptation needed. Sourced from Multiquip's authorized parts supply, the part is the right choice when maintaining your BLW-400SSW welder to its original operating standard.

Key Features

• Genuine OEM Sealing Specification — Manufactured to exact thread pitch and seating dimensions required to maintain a leak-free seal at the oil filter port.
• Direct Drop-In Replacement — Threads directly into the factory oil filter port on BLW-400SSW welders, restoring the original oil system closure point.
• Confirmed Fitment — Verified for compatibility with the Multiquip BLW-400SSW welder; check your model plate before ordering.
• Protects Engine Oil Pressure Integrity — A correctly seated oil filter plug prevents oil loss and maintains the lubrication circuit your engine depends on during continuous welding operation.
• Safety-Relevant Fuel and Fluid Retention — An improperly sealed or missing oil filter plug can lead to rapid oil loss, engine damage, and unsafe operating conditions — using the correct OEM plug eliminates that risk.

The oil filter plug seals the oil filter housing or filter port on the engine, keeping the lubrication system closed and pressurized during operation. It prevents oil from escaping the filter circuit when the filter is not installed or during maintenance intervals. A missing, damaged, or incorrect plug can cause immediate oil loss, loss of lubrication pressure, and accelerated engine wear — making it a small part with significant consequences for the longevity and safe operation of the machine.
