3-Inch Washpipe Assembly
Lower Spacer Function
The lower spacer is one of the individual spacer components used within the 3-inch washpipe packing arrangement. It works together with the upper spacer, middle spacer, packing seals, retaining components, and washpipe hardware as part of the complete assembly.
Part Number 30123287 is specifically identified as the lower spacer and should not be confused with the upper or middle spacer. Each spacer occupies a specific position within the washpipe assembly and has its own part number.
Related Washpipe Components
A compatible 3-inch washpipe arrangement may include an upper spacer, middle spacer, lower spacer, holding ring, snap ring, washpipe, packing seals, packing box, grease fitting, and dedicated securing hardware.
These components work together within the washpipe system and should always be identified according to the applicable equipment documentation and manufacturer part numbers.
NOV Top Drive Application
Washpipe System in Top Drive Equipment
The washpipe assembly is part of the drilling fluid circulation system in a top drive. It allows drilling fluid to pass through rotating drilling equipment while supporting the mechanical and sealing requirements of the system.
Spacer components help maintain the intended positioning of the packing and washpipe components within the assembly. Correct installation and identification are important during maintenance and rebuild operations.
NOV / Varco TDS Applications
Legacy Part Number 30123287 is listed in parts references for NOV / Varco top drive equipment, including TDS-11SA applications. Customers maintaining this equipment may encounter the part number in spare parts catalogs, maintenance documentation, equipment drawings, and previous purchasing records.
Maintenance and Replacement
Washpipe Service Components
Washpipe assemblies operate in demanding drilling conditions involving rotation, drilling fluid, pressure, vibration, and continuous mechanical operation. Individual spacers and related components may therefore require inspection or replacement during scheduled maintenance.
When servicing the washpipe assembly, the condition and position of each spacer should be checked according to the applicable NOV maintenance procedures.
Correct Spacer Identification
Upper, middle, and lower washpipe spacers may appear similar but have different positions and part numbers. Replacement components should therefore be selected using the specified manufacturer part number rather than appearance alone.
For this component, the key references are NOV Lower Washpipe Spacer 30123287 and Oracle Part Number 10375862-001.
Part Number Cross Reference
10375862-001 and 30123287
This component may be referenced by Oracle Part Number 10375862-001 or Legacy Part Number 30123287. Keeping both numbers in purchasing and maintenance records can assist customers working with different generations of NOV equipment documentation.
The product description “Lower Spacer, 3 Inch Washpipe” also helps distinguish this component from the upper and middle washpipe spacers used in the same assembly.
