Multiquip EM916004 Lube Fitting

The Multiquip EM916004 Lube Fitting is a genuine OEM component designed for the Mayco C30HD concrete pump. Sourced directly from Multiquip, this fitting matches the original specification installed at the factory, ensuring a correct, hassle-free installation without guesswork. If you're servicing or rebuilding a C30HD, using the correct OEM lube fitting helps protect lubrication points and keeps the pump running at full capacity.

Key Features

• Genuine OEM Construction — Manufactured to the exact thread form, material grade, and seating geometry required for a concrete pump lubrication system, eliminating the risk of poor thread engagement or grease bypass.
• Direct Installation — Threads directly into the designated lubrication port on the C30HD with no reworking or adapter needed, matching the original fitting seat.
• Confirmed Fitment for C30HD — Verified for Mayco C30HD cycloidal-drive concrete pumps, so you can order with confidence against your machine's existing port.
• Protects Critical Lubrication Points — A properly seated lube fitting delivers grease exactly where moving components need it; a damaged or cross-threaded fitting starves those surfaces and accelerates wear.
• Long-Term Corrosion Resistance — OEM-specified material construction stands up to the moisture, concrete slurry, and grit exposure typical on active pump sites.

A lube fitting — commonly called a grease fitting or zerk fitting — is the small threaded port that accepts a grease gun coupler and allows lubricant to be forced into bearings, pivots, or other wear surfaces under pressure. On a concrete pump like the C30HD, keeping these fittings intact and properly seated is essential: a missing, stripped, or leaking fitting means grease cannot reach the internal components it protects, leading to accelerated bearing or bushing wear and potentially a costly pump failure. Replacing a damaged fitting promptly with the correct OEM part is one of the lowest-cost, highest-impact maintenance steps an operator can take.
