Multiquip 9099022990 Rocker Oil Feed Nipple

The Multiquip 9099022990 Rocker Oil Feed Nipple is a genuine OEM component designed for DCA25SSAI, DCA25SSI, DCA25SSI2, DCA25SSIU, and DCA25SSIU-GEER ultra-silent diesel generators. As an authorized Multiquip OEM part, the part is manufactured to the exact specifications of the original, ensuring a direct, correct-fit installation with no guesswork. Sourced directly through Multiquip's OEM supply chain, this nipple is the same component installed during original production, giving you confidence in compatibility and longevity across the DCA25SS generator series.

Key Features

• Genuine OEM Oil Passage Integrity — Manufactured to exact dimensional tolerances to maintain proper oil flow volume and pressure to the rocker assembly, preventing starvation-related wear.
• Direct OEM Replacement — Matches the original fitting thread pitch and seat geometry for a drop-in installation on DCA25SS series engines.
• Broad DCA25SS Series Coverage — Confirmed fitment across DCA25SSAI, DCA25SSI, DCA25SSI2, DCA25SSIU, and DCA25SSIU-GEER ultra-silent generator models.
• Sustained Rocker Lubrication — A correctly functioning oil feed nipple ensures the rocker arm and valve train receive consistent lubrication; a clogged or damaged nipple can lead to rapid valve train wear and engine damage.
• Engine Protection Compliance — Using the correct OEM nipple safeguards oil circuit integrity in a fuel system-adjacent lubrication path, supporting safe, uninterrupted generator operation.

The rocker oil feed nipple is a small but critical fitting within the engine's valve train lubrication circuit. It routes pressurized oil from the engine block up to the rocker arm assembly, keeping the rocker arms, pushrods, and valve stems properly lubricated during operation. When this nipple becomes clogged, cracked, or fails to seal correctly, oil delivery to the rocker assembly is disrupted, which can cause accelerated valve train wear, increased engine noise, and ultimately engine damage if left unaddressed.
