Wacker Neuson 5000089385 O-Ring 3/8X1/16-70 Shore A

The Wacker Neuson is a genuine OEM O-Ring 3/8X1/16-70 Shore A designed for WP, VP, AP, and MP series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, this O-ring matches the original factory component in material grade, dimensional tolerancing, and Shore A hardness rating. Compatible models span a wide range of the WP1540, WP1550, VP1135, VP1340, VP1550, VP2050, AP1135, AP1550, MP12, MP15, and MP20 series plates, making it a commonly needed seal across the vibratory plate lineup. Confirm your model number against the fitment list before ordering to ensure an exact application match.

Key Features

• 70 Shore A Hardness Rating: — Matched to the original specification, this hardness grade provides the correct compression and sealing force for the hydraulic or fluid passage it seats against — too soft or too hard causes leaks.
• Genuine OEM Material Grade: — As an authentic Wacker Neuson part, the elastomer compound is selected for compatibility with the fluids and operating temperatures found in these vibratory plate compactors.
• Drop-In Replacement: — The 3/8 x 1/16 cross-section dimensions match the original groove geometry, so the ring seats correctly without modification to the mating surfaces.
• Broad Series Coverage: — A single part number covers WP1540, WP1550, VP1135, VP1340, VP1550, VP2050, AP1135, AP1550, MP12, MP15, and MP20 series vibratory plates, making it a practical stocking item for fleets running multiple Wacker Neuson plate models.
• Sealing Integrity: — A correctly seated O-ring prevents fluid or air bypass at the joint it seals, maintaining consistent hydraulic or pneumatic pressure and protecting surrounding components from contamination or moisture ingress.

An O-ring is a loop-shaped elastomeric seal that sits in a machined groove between two mating surfaces or fittings. Its function is to block the passage of fluid, air, or contaminants across that joint under both static and dynamic conditions. When an O-ring degrades — through compression set, chemical attack, or physical damage — it loses its ability to conform to the seating surface, and leaks develop that can lead to pressure loss, fluid contamination, or accelerated wear on adjacent components. Replacing a worn O-ring promptly with the correct size and hardness rating restores the sealing integrity of the assembly and prevents broader damage.
