The Multiquip 491700 Grease Fitting Cap 1/4" NPT is a genuine OEM component designed for Essick Mixer equipment. As a direct OEM replacement, this cap ensures the correct thread specification and sealing profile for 1/4" NPT grease fittings on your machine. Sourced directly from Multiquip, part 491700 is the exact component your equipment was built with, keeping your lubrication points protected and service-ready.
Key Features
- OEM Thread Accuracy — Matched to the 1/4" NPT thread spec used on Essick Mixer grease fittings, so the cap seats and seals correctly without cross-threading risk.
- Contamination Defense — Caps exposed grease fittings between service intervals to block dirt, grit, and moisture from entering lubrication points and causing premature bearing wear.
- Direct OEM Replacement — Genuine Multiquip part 491700 installs directly onto existing 1/4" NPT Zerk fittings with no additional hardware needed.
- Verified Essick Mixer Fitment — Confirmed for Essick Mixer series equipment; cross-reference your model before ordering to ensure compatibility.
- Protects Long-Term Lubrication Integrity — A missing or damaged grease fitting cap allows abrasive debris to pack around the fitting, making proper greasing difficult and accelerating wear on critical rotating components.
A grease fitting cap is a small but important protective cover that threads onto a standard Zerk-style grease fitting when it is not actively in use. Its job is to keep contaminants — including dirt, concrete dust, and water — from clogging or corroding the fitting between lubrication intervals. When a cap is missing or cracked, debris can block the grease passage entirely, making it impossible to deliver lubricant to bearings and pivot points, which leads to accelerated component wear and potential mechanical failure.
