2026-11-03

This action is to establish a Requirements Contract for the acquisition of the HC / MC - 130 Aerial Nozzle Press ( Hereafter referred to as the Coupler or Coupling ), National Stock Number ( NSN ): 1680 - 01 - 530 - 3831 , Part Number ( P / N ): 50725 , which is a non - commercial item that is applicable to the HC / MC - 130 Aircrafts . The Coupling National Stock Number ( NSN ): 1680 - 01 - 530 - 3831 , Part Number ( P / N ): 50725 , is attached to the refueling hose just AFT of the ejection spring . The coupling consists primarily of a housing , locking mechanism , poppet valve , and connector . The coupling also includes a hose end pressure regulating feature which pre - vents surges in fuel delivery pressure , which prevents damage to fuel system components on the receiver airplane , and also to an extent on the tanker airplane . The housing is cone shaped to guide the entrance of the mating nozzle on the receiver airplane . There are three locking mechanisms , consisting of spring - loaded pistons , eccentrically attached to arms and rollers . Insertion of the receiver probe nozzle actuates the arm and roller assemblies . Passages are provided in the housing to allow a sample of fluid pressure into piston chambers of locking mechanisms . This fluid pressure , tapped from the fuel flow passing to the receiver airplane , adds pressure to the roller locking mechanisms to in - crease the force required for disconnect to420 ± 20 pounds . The spring - loaded closed poppet valve is mounted in a ball - shaped housing extension . The poppet valve is opened by the tip of the receiver airplane probe nozzle upon its insertion . The connector , with a ring and connector cap , forms a socket for the ball shaped housing extension . The Government does not own the technical data package for this item . This requirement will be solicited sole source to manufacturer BLUEAEROSPACE LLC ( CAGE 1WZW9 ) pursuant to 10 USC 2304 ( c )( 1 ); FAR 6 . 302 - 1 . All responsible sources may submit a capability statement , proposal or quotation , which shall be considered by the agency .
