PSC 4930

Overview

The Product Service Code (PSC) system is a governmentwide taxonomy used to classify the products and services bought by U.S. federal agencies. PSCs appear in reporting systems such as FPDS and SAM.gov and are governed through the PSC Manual on Acquisition.gov to enable consistent tracking, analysis, and spend transparency. ²

PSC 4930 identifies “Lubrication and Fuel Dispensing Equipment.” The PSC Manual specifies examples such as hand grease guns, centralized lubrication systems, hydrostatic lubricators, oil and gasoline dispensing pumps, fuel oil dispensing pumps, hand oilers, grease dispensers, pressure gun attachments, and sight feed lubricators. It excludes Alemite and other lubrication fittings, which are classified under PSC 4730. ¹

What this PSC covers

• Hand-operated grease guns used for equipment lubrication. ¹
• Centralized lubrication systems for machinery and vehicles. ¹
• Hydrostatic lubricators supplying pressurized lubricant flow. ¹
• Oil and gasoline dispensing pumps for fueling operations. ¹
• Fuel oil dispensing pumps for storage and transfer points. ¹
• Hand oilers and portable grease dispensers. ¹
• Pressure gun attachments and sight feed lubricators. ¹

Reporting and environmental attributes in FPDS

• PSC is recorded in FPDS data element 8A; select the code representing the predominant item on the action. ¹
• Environmental attributes (e.g., energy efficient, biobased, environmentally preferable) are captured in FPDS data element 8L when applicable. ¹
• The PSC Manual provides definitions and examples to support selection of environmental attributes alongside the PSC entry. ¹

Frequently asked questions

• What items are included under PSC 4930?

  • The PSC Manual lists hand grease guns, centralized lubrication systems, hydrostatic lubricators, oil and gasoline dispensing pumps, fuel oil dispensing pumps, hand oilers, grease dispensers, pressure gun attachments, and sight feed lubricators as examples within PSC 4930. ¹

• Are lubrication fittings or connectors coded under PSC 4930?

  • No. Lubrication fittings (e.g., Alemite fittings) are coded under PSC 4730, which the PSC Manual lists as an explicit exclusion from PSC 4930. ¹

• Does PSC 4930 cover centralized lubrication systems for industrial equipment?

  • Yes. Centralized lubrication systems for machinery or vehicles are expressly included under PSC 4930, covering systems that distribute lubricants to multiple points to reduce wear and maintenance frequency. ¹

• How is PSC 4930 entered in FPDS, and are environmental attributes required?

  • Enter the PSC in FPDS element 8A based on the predominant product or system on the action. When applicable, select environmental attributes in element 8L consistent with the PSC Manual’s definitions and the item being procured. ¹

• Are aircraft refueling trucks or in-flight refueling components classified under PSC 4930?

  • Not specified by official sources. The PSC Manual does not provide an explicit rule for aircraft refueling trucks or in-flight refueling components within PSC 4930; classification depends on the item’s exact characteristics and applicable PSC notes. ²
