About this file
This is a procurement specification document for spare parts to support Kennedy Space Center Propellants & Life Support Services (KPLSS) equipment used in Artemis systems.
The procurement covers six spare part components for the Compressor/Converter Facility (CCF) and related systems that provide high-pressure helium, low- and high-pressure nitrogen, breathing air, and oxygen. Components are needed to maintain minimum inventory levels for the Artemis III program and minimize outages. All items must be delivered to NASA/Kennedy Space Center, BOSS Warehouse M6-0744, Kennedy Space Center, FL 32899, with attention to KPLSS Terrie Hydorn or NASA Steven Shelley. Requested items include: one Anderson Greenwood 3/4" FNPT relief valve (81SF68-4) cleaned to 1000A; one Rosemount pressure transducer multivariable transmitter (4088B1P13G4R2A111AL1Q4) cleaned to ASTM B40.1-1988 Level IV; four Tescom components including a fluid pressure regulating valve (1 unit, cleaned to 1000A), a pressure regulator (1 unit, cleaned to 1000A), an angle valve (12 units, cleaned to 100A), and a globe valve (1 unit, cleaned to 300A). All components require specified cleaning per ASTM G93 through full disassembly and reassembly unless otherwise noted, with certificates of conformance required upon delivery. Quotes must include estimated Average Repair Overhaul (ARO) costs and any additional lead times from manufacturers.

Procurement of EGS Spare Parts, CCF
1.0 Background
Procurement of these components is necessary to ensure spare parts are available for Kennedy Space Center Propellants & Life Support Services (KPLSS) equipment to support Artemis systems, including the Compressor/Converter Facility (CCF), commodity lines, rechargers, and panels. These systems provide high-pressure helium, low- and high-pressure nitrogen, breathing air, and oxygen. Spare parts are required to be purchased to have on-hand in the event of component failure, to minimize outages and provide continued support to Exploration Ground Systems (EGS). This purchase is for spare parts to support this effort. Each system has certain cleaning requirements, per KSC-C-123. Cleaning specifications are noted for components using this standard, which is similar to industry standard ASTM G93 and ANSI/ASTM B.40.1.
2.0 Requirements
The following are the components needed to ensure EGS has the minimum number of spares needed for Artemis III. Quotes must have estimated AROs and any additional lead time from the manufacturer. Specified cleaning is requested to be completed by the vendor per ASTM G93 specifications through a full disassembly and reassembly process, unless otherwise noted to be flow-through or to use ASTM B40.1, prior to shipment to Kennedy Space Center. A certificate of conformance shall be included with the delivery of the component.
