The Multiquip MM433353 Relief Spring BLW-300 is a genuine OEM component designed for BLW-300 series equipment. Sourced directly from Multiquip, this spring carries the same specifications as the original part installed at the factory, ensuring correct tension, travel, and response characteristics right out of the box. If you're servicing a BLW-300 and need a spring you can trust to perform exactly as intended, MM433353 is the correct replacement. DHS Equipment stocks genuine Multiquip OEM parts so you can order with confidence and get your machine back to work fast.
Key Features
- Genuine OEM Spring Tension: — Manufactured to the exact coil rate and free-length spec of the original, so relief activation occurs at the correct threshold — not too early, not too late.
- Direct Drop-In Replacement: — Engineered to the same dimensions and end-configuration as the original MM433353 spring, seating correctly in the BLW-300 relief circuit without modification.
- Confirmed BLW-300 Fitment: — Designed specifically for the BLW-300, eliminating guesswork when sourcing service parts for this model.
- Maintains Proper Relief Function: — A correctly rated relief spring keeps system pressure within its designed operating range; a fatigued or incorrectly rated spring can cause pressure drift, erratic operation, or component damage.
- Genuine Multiquip OEM Quality: — Produced to Multiquip's material and heat-treatment standards for spring steel, delivering the fatigue resistance and consistent load characteristics that a high-cycle relief application demands.
A relief spring is a critical load-bearing element inside a pressure relief valve or relief circuit. Its job is to hold the valve closed against system pressure until that pressure reaches a set point — at which moment the spring compresses, the valve opens, and excess pressure is safely vented or bypassed. The calibrated tension of the spring is what defines that set point, so spring condition directly controls where and how precisely the system relieves. When a relief spring weakens, takes a set, or breaks, the relief point shifts — leading to pressure that is either too high (risking component damage) or too low (causing sluggish or incomplete operation). Replacing a worn spring with the correct OEM-spec MM433353 restores the relief circuit to its intended performance range.
