Lunar Module CouplerThis is a NASA Apollo Lunar Module Flight Spare coupler from the Spacecraft's Rocket Propulsion System. This Aerospace Grade stainless steel fitting originally belonged to a Kennedy Space Center engineer who worked at NASA during the Apollo era.
This artifact was designed as part of the hypergolic propulsion fuel or oxidizer system aboard the LM Spacecraft and has documentation and quality control information from Grumman.
Grumman Aircraft Engineering Corporation (GAEC) was the prime contractor for the Apollo LM.
This critical component was originally double sealed in the Grumman/NASA Mylar and Polyethylene packages. The outside package became brittle and broke into many tiny pieces. The coupler remains sealed in the inner seal.
