Conduits are sort of the general purpose "thing" to either go wrong or to have to fix on a spaceship. You could replace an entire spaceship combat hit location table with the following:

d%	Location
1-100	Conduit

It'd be just as effective. Or for bonus points add the following:

d%	Conduit type
1-4	Antimatter
5-8	Baryon
9-12	Entropy
13-16	Ferrofluid
17-20	Flux
21-24	Heisenfram
25-28	Hydraulic
29-32	Hydrocolloid
33-36	Hyperfluid
37-40	Intermix
41-44	Laser
45-48	Liquid helium
49-52	Liquid sodium
53-56	Microwave
57-60	Neutrino
61-64	Neutron beam
65-68	Non-Newtonian fluid
69-72	Phlebotinum
73-76	Plasma
77-80	Quasi-crystal
81-84	Steam
85-88	Superfluid
89-92	Tachyon
93-96	Vortex
97-100	Wavelet

Han: Hey, what'cha doing there?
Leia: Chewie asked me to weld this joint and seal this conduit.
Han: Huh. He didn't ask me to do anything.
Leia: Han, I have a personal question to ask you.
Han: Yes?
Leia: Is Chewbacca single?
Han: What?
Leia: He's so charming and wellspoken and chivalrous and handsome. I don't understand how a guy like that doesn't have a partner.
Han: I'm his partner!
Leia: No, I mean a... mate.
Han: I'm his best mate!
Leia: I'm talking about a special friend.
Han: I'm pretty special!
