The Multiquip APRD27807 Flat Washer 5/8" SAE is a genuine OEM component designed for AP6 and AP8 series water pumps. As a direct OEM replacement, APRD27807 meets the original dimensional and material specifications Multiquip requires for proper fastener clamping and load distribution on these units. Sourced directly through authorized supply channels, this washer is verified to fit AP6 and AP8 equipment without substitution or guesswork.
Key Features
- OEM-Grade Material Consistency — Manufactured to the same SAE flat washer standard as the original, ensuring correct hardness and surface finish for proper load bearing across fastened joints.
- SAE 5/8" Specification — Sized to the SAE standard for 5/8" fasteners, seating flush against mating surfaces for even clamp load distribution without distortion.
- Direct OEM Replacement — Replaces the original washer on AP6 and AP8 water pumps with no sizing adjustments needed at installation.
- Confirmed Fitment for AP6 and AP8 — Verified for Multiquip AP6 and AP8 water pump models, so you can order with confidence.
- Prevents Fastener Pull-Through and Surface Damage — A correctly sized flat washer distributes clamping force evenly; an undersized or worn washer allows fastener pull-through, loosening, and surface damage to pump housings and covers.
A flat washer acts as a load-spreading interface between a fastener head or nut and the surface it clamps against. By distributing clamping force over a wider area, it prevents the fastener from pulling through softer materials, protects mating surfaces from damage during torquing, and helps maintain consistent joint tension over time. On water pump assemblies like the AP6 and AP8, flat washers appear throughout covers, housings, and mounting points — when a washer is missing, deformed, or the wrong size, fasteners can work loose under vibration, leading to leaks or structural movement in critical joints.
