Patent ID: 6883836

Claim:
A positive locking fitting assembly for interconnecting a pair of modular components, said assembly comprising: (a) a pair of couplers spaced from one another and each coupler connected to a corresponding modular component, each coupler comprising: (i) a modular fitting attached to the corresponding modular component, said modular fitting having a first end residing adjacent an inner surface of the modular component, and a second threaded end residing adjacent an outer surface of the corresponding modular component; (ii) a jam nut threadably received over said second threaded end of said modular fitting, said jam nut having a first locking means disposed thereon; (iii) a lock nut positioned adjacent said jam nut, said lock nut having a second complementary locking means that contacts said first locking means to place said lock nut in a locked position, said lock nut being biased to facilitate locking of said second complementary locking means with said first locking means, and said second complementary locking means not contacting said first locking means when said lock nut is in an unlocked position; (b) a transfer tube placed between said pair of couplers and spanning a gap between the modular components; and (c) means for sealing said transfer tube against said pair of couplers.
