The MAKITA 213977-2 is an OEM-authorized O-Ring 7 replacement part manufactured in the United States. O-rings provide critical sealing within tool assemblies, preventing fluid or air leakage at mating surfaces and maintaining internal pressure integrity. This part is made from plastic-compatible materials and is a direct OEM replacement, meaning it meets original factory specifications. Weighing just 0.01 pounds, it is a small but essential component for restoring proper function to compatible Makita power tools. Technicians performing tool maintenance or repair will recognize this as a precision fit seal designed to spec.
This O-ring is intended for use in Makita power tool service and repair applications. It fits various Makita models as noted by the manufacturer. Installation is typically performed during scheduled maintenance, after seal failure, or as part of a broader internal component rebuild. Trade professionals and authorized service technicians are the primary installers of OEM seal components such as this one.
Designed as an OEM-style replacement seal for use in compatible Makita power tools as specified by the manufacturer. Consult your Makita service manual or parts diagram to confirm fitment for your specific model before ordering.
O-ring replacement should be performed by a qualified service technician familiar with Makita tool disassembly procedures. Disconnect and de-energize the tool completely before beginning any internal service work. Take care not to nick or roll the O-ring during installation, as surface damage will compromise the seal. Refer to the applicable Makita service documentation for proper assembly sequence and torque guidance.
