Fisher Space Pen PRESSURIZED CARTRIDGES
Fisher Space Pen’s Sealed Pressurized Ink Cartridge
Performs in temperatures from -30ºF to +250ºF, underwater, in zero gravity, at
any angle–even upside down! The ultimate in dependability! The choice of ski
patrols, search and rescue teams, law enforcement agencies, armed forces, and
everyone who demands reliability in a writing instrument
ALL Fisher Space Pens use our PR Cartridge (except the Q4)
The following image is enlarged to show detail.
The PR Cartridge is the fat one in the middle. The U Cartridge is the skinny one on the top and bottom. When it arrives
it will be long like the top image shows. It is made this way to fit several different pen barrels. If you need
it to be shorter, just flex it back and forth at the break point and it will separate, leaving you the correct length
The PR and U cartridges are NOT INTERCHANGEABLE!
Please note: the U
Cartridges contain a much smaller amount of ink, they write about
1200 feet depending on your writing style, as compared to our regular PR Cartridge
which should write more than 12,000 feet depending on style and surface.
ALL PR cartridge come with a plastic adapter which allows them to be used in Parker Style Pens!
