About this file
This is a procurement document for spare parts to support Kennedy Space Center Propellants & Life Support Services (KPLSS) equipment used in Artemis systems. The procurement is necessary to maintain on-hand inventory of spare parts for Kennedy Space Center's high-pressure helium, nitrogen, breathing air, and oxygen systems, enabling rapid component replacement to minimize operational outages and support Exploration Ground Systems (EGS).
The solicitation specifies nine components from two manufacturers: eight items from Tescom and one item from Flexim. Tescom components include hand regulators, globe valves, pressure regulators, angle valves, regulating valves, and valve kits in quantities ranging from one to ten units, with cleaning requirements specified to either 100A or 300A standards per ASTM G93 or ASTM B40.1, to be completed through full disassembly and reassembly prior to shipment. The Flexim component is a G704 Dual-Channel Permanent Gas Flowmeter with Pressure and Temperature Inputs, with a quantity of two units. All quotes must include cleaning specifications, estimated Annual Reorder Quantities (AROs), additional lead times from manufacturers, and a certificate of conformance with delivery. Soft good kits are exempted from disassembly and reassembly requirements. Delivery location is NASA/Kennedy Space Center BOSS Warehouse M6-0744, Kennedy Space Center, FL 32899.

Procurement of EGS Spare Parts, non-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 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.
2.0 Requirements
The following are the components needed to ensure EGS has the minimum number of spares needed for Artemis III.
2.1. Quotes must have cleaning specifications, estimated AROs, and any additional lead time from the manufacturer.
2.2. 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.
2.3. Soft good kits do not require a disassembly and reassembly process.
2.4. A certificate of conformance shall be included with the delivery of the component.
