Oracle and Legacy Part Numbers
The component may appear under more than one part reference depending on the age of the equipment documentation or purchasing system. Legacy Part Number 30123564 is widely referenced in top drive spare parts lists, while Oracle Part Number 10375898-001 provides the corresponding newer reference supplied for this item.
When requesting this component, providing both numbers can help simplify identification and reduce confusion between older maintenance records and current purchasing documentation.
Socket Head Dog Nose Screw Design
Washpipe Fastening Application
The NOV Washpipe Cap Screw 30123564 is identified as a socket-head dog-nose screw used in the washpipe system. The dog-nose design distinguishes this component from conventional cap screws and helps identify its intended use within the applicable assembly.
Washpipe assemblies contain several specialized components including packing boxes, rings, spacers, seals, wash pipes, and dedicated fastening hardware. Each component should be selected according to the specified part number and equipment documentation.
Importance of Correct Fastener Selection
Fasteners used in drilling equipment may vary in thread size, length, material, head design, and application. Components that appear visually similar should not automatically be considered interchangeable.
For this reason, the correct manufacturer part number should be used when sourcing a replacement. For this item, the primary references are NOV Washpipe Cap Screw 30123564 and Oracle Part Number 10375898-001.
NOV Top Drive Washpipe Assembly
Part of the Washpipe System
The washpipe assembly is part of the drilling fluid circulation system in a top drive. It allows drilling fluid to pass through the rotating top drive equipment while supporting the sealing and mechanical requirements of drilling operations.
The washpipe system includes a number of individual components that work together as an assembly. The socket-head dog-nose screw identified by Part Number 30123564 is one of the dedicated components associated with this system.
TDS-11SA Top Drive Application
Legacy Part Number 30123564 is listed in spare parts references for the NOV / Varco TDS-11SA top drive. The TDS-11SA is a 500-ton top drive system manufactured by NOV and used in drilling applications.
Customers maintaining TDS-11SA equipment may encounter Part Number 30123564 in spare parts catalogs, maintenance records, previous purchase orders, or equipment documentation.
Washpipe Maintenance and Replacement
Replacement Fasteners
Washpipe components operate in demanding drilling environments involving rotation, pressure, vibration, drilling fluids, and repeated operating cycles. Fasteners associated with these assemblies should therefore be inspected according to the applicable equipment maintenance procedures.
If a washpipe assembly is being serviced or rebuilt, individual hardware components should be checked for condition and replaced where required according to the manufacturer’s instructions.
Verify the Part Before Ordering
Before ordering, customers should confirm the required part number against the equipment parts list or maintenance manual. Where available, the top drive model, serial number, existing part number, and washpipe assembly information should also be provided.
Thread size, length, material grade, and other dimensional specifications should be confirmed from applicable NOV technical documentation rather than estimated from the appearance of the component.
Part Number Cross Reference
30123564 and 10375898-001
This washpipe cap screw can be referenced by Legacy Part Number 30123564 and Oracle Part Number 10375898-001. Including both numbers in an inquiry helps procurement teams cross-reference the component across different generations of equipment documentation.
This is particularly useful for drilling equipment that has remained in operation for many years and may have maintenance records containing legacy Varco or NOV part numbers.
