3-Inch Washpipe Assembly
Middle Spacer Function
The middle spacer is one of the individual components used within the 3-inch washpipe packing arrangement. The washpipe system contains several components that must be installed in their specified positions to form the complete assembly.
The NOV Middle Washpipe Spacer 30123286 should not be confused with the upper or lower washpipe spacers. Each spacer has its own part number and specified position within the washpipe arrangement.
Related Washpipe Components
Components associated with a compatible 3-inch washpipe arrangement may include the washpipe assembly, packing box, upper spacer, middle spacer, lower spacer, holding ring, snap ring, packing seals, grease fitting, and dedicated fastening hardware.
These components work together as part of the washpipe system. Replacement parts should therefore be identified using the applicable manufacturer part numbers rather than appearance alone.
NOV Top Drive Application
Washpipe System in Top Drive Equipment
The washpipe assembly provides part of the drilling fluid path through rotating top drive equipment. During drilling operations, the system must support fluid circulation while operating under demanding mechanical and pressure conditions.
Spacers and packing components form part of the washpipe arrangement and help maintain the specified positioning of individual components within the assembly.
NOV and Legacy Varco Equipment
Part Number 30123286 is widely listed among replacement components for NOV and legacy Varco top drive washpipe systems. Customers maintaining this equipment may encounter the part number in maintenance records, service documentation, drawings, parts catalogs, and previous procurement records.
NOV continues to support a range of top drive systems, including the TDS-11SA platform used in drilling operations worldwide.
Maintenance and Replacement
Washpipe Service Components
Washpipe assemblies operate under demanding drilling conditions involving rotation, drilling fluid, pressure, vibration, and continuous equipment operation. Individual packing and spacer components may therefore require inspection or replacement as part of scheduled maintenance.
When servicing a washpipe assembly, each spacer and related component should be checked according to the applicable equipment maintenance procedures.
Correct Spacer Identification
Upper, middle, and lower washpipe spacers can have different dimensions and functions even when they appear similar. Selecting the correct position and part number is therefore important when rebuilding or repairing the washpipe assembly.
For this component, the key identification reference is NOV Middle Washpipe Spacer 30123286, together with Oracle Part Number 10375861-001 and previous Part Number 123286.
Part Number Cross Reference
10375861-001, 30123286 and 123286
This component may be identified using three references:
- Oracle Part Number: 10375861-001
- Legacy Part Number: 30123286
- Previous Part Number: 123286
Part Number 30123286 replaces 123286. Keeping all three references available can assist customers searching through different generations of equipment documentation and spare parts records.
