Manufactured by Monarch Industries Inc, this seal kit is designed as a direct replacement component for maintaining hydraulic units that require part number 639575. Seal kits of this type typically contain the necessary O-rings, seals, and related components needed to restore proper sealing performance in hydraulic power units during routine maintenance or after wear-related fluid loss.
The Monarch 639575 Seal Kit is sourced directly from the original equipment manufacturer, helping to ensure compatibility with the corresponding Monarch hydraulic unit. Using OEM seal kits supports consistent fit and reduces the risk of premature failure associated with non-specified replacement parts.

Question by: Tommy A on Feb 13, 2025, 9:11 PM
got a monarch cylinder that needs rebuilding, will this 639575 kit work for it?
Answer by: Customer Support on Feb 15, 2025, 8:17 AM
Without knowing your specific cylinder model number, there's no way to confirm compatibility. Monarch produces hundreds of different cylinders, each requiring its own unique seal configuration with different bore sizes, rod diameters, and seal groove specifications. You'll need to match this 639575 kit number against your cylinder's parts breakdown or nameplate information to verify it's the right fit.
