SU Series  BLACK Ink / FINE Point Cartridges
This listing is for FOUR (4) New SU Series Fisher Space Pen BLACK Ink / Fine Point Cartridges for the Triple Action TAN, TAN-S, TAG-S, or Q4 pens. NOTE: All SU Series Universal ink refills are fine point. This refill can be put in place of one of the other positions. A lot of our customers tell me they take out the stylus because they have no use for it and replace it with the Blue Ink refill. Because of the small diameter ink refills in these Multi Function pens the ink refills do not last as long as standard refills, nor do they cost as much. It is proportionate. We would advise you to keep several extras on hand. These are the Fisher "SU" Series refills and also fit Retro 51 Elite Series Pens, Autopoint, Chromatic Mirage, Niji, Sharbo, Zebra and most Multi-color Pens, Including Fishers Q4 and Acmes 4FP quad action pens.
NOTICE:
*These do not fit Fisher single point pens (like the Bullets)
*They take the SPR Series Refills
Pen Compatibility for this Refill:
The Fisher Multi-Function Pens, the TAG-S and the Q-4, Take the SU Series Refills Only. These are also known as the UNIVERSAL refills. They do NOT fit the regular Fisher line like the Bullets and Astronauts that take the SPR Series Refills. These also fit Retro 51 Elite Series Pens, Autopoint, Chromatic Mirage, Niji, Sharbo, Zebra and most Multi-color Pens, Including Fishers Q4 and Acmes 4FP quad action pens. They also fit the Victorinox knives that have the ink pen. The SU refills are pressurized and will write at any angle just like the SPR Series refills. However the SU series only come in three colors; Black, Blue and Red and all three are fine point only. Because of the limited space of putting three or four refills in one pen they have a smaller diameter, and are segmented so they can be broken off to different lengths to fit in smaller spaces than the standard refills. Therefore they do not hold as much ink and will need to be replaced more frequently. They are also a lot cheaper than the standard refills so it all averages out. Just be aware that you should keep some refills on hand. The refill diagram shown below is a SPR Series refill not the SU Series. But it shows the principle behind the pressurized refill. One of the photos shows the SPR Series Refill and the Universal SU Series Refills together for comparison. This will help you get the right refill for your pen.
About Fisher Space Pens:
Fisher Space Pen is yet another great breakthrough from space research. No other pen has so much to offer. This pen was designed in 1965 by Paul C. Fisher, for NASA, and with no cost to NASA or our government. Ordinary pens rely on gravity to write. Hold them upside down and they quit. There was a need for a pen that would work in the zero gravity vacuum of space, and in extreme conditions. Paul Fisher developed such a pen. For the ink cartridge to write at any angle the cartridge was charged with 35 PSI of nitrogen. A small ball type float was used to separate the gas charge from the ink and it had to be hermetically sealed to hold the charge. With that type of pressure a precision fit stainless steel machined socket with a tungsten carbide ball and a specially formulated thixotropic ink was used keep the pen sealed and leak free. Fisher Space Pens have been used on EVERY Space Shuttle mission, both USA and Russian. They were also featured on a Seinfeld episode. ..... Imitated but never duplicated..... Because it is hermetically sealed it will not dry out like other pens and has a shelf life of over a hundred years. It does not rely on Gravity, It writes upside down, in the vacuum of space, on wet paper, underwater, in the freezing cold of -30° F, and the boiling heat of 250° F. Fisher Ink cartridges stay leak free and writing longer, cleaner, and more consistently than any other ink cartridges. Fishers are not only utilized by Astronauts but the Thunderbirds, the Blue Angels, the Navy Seals, and the Canadian Snowbirds also use the Fisher pen. Fishers are favorites among Firefighters, Paramedics, and Police Officers. We have even sold them to Tow Truck operators is Alaska that needed a pen to write in subzero conditions. If you count on a pen to work, you need a pen with a Fisher ink cartridge. The Fisher Bullet Pen was exhibited at the New York Museum of Modern Art. It has been featured on the Tonight Show, Good morning America, John Ratzenberger's Made in America, and an episode of Seinfeld. Still proudly made here in the USA and I can tell you first hand Fisher Space Pen Company is made up of great people. Fisher has a wide variety of pens to fit almost anyone’s wants and needs in a variety of price ranges. Pens from the economy line that are gas pressurized, Plastic barrels, and not refillable at about .00 to the Infinium Series Pens that is warranted to never run out of Ink for a lifetime at about 0.00. Of course, there are many series in between so you are sure to find the pen that fits your needs and style. All of this brings me ask the question, “Sure you could buy another pen, but why would you?” Fisher refills come with an adapter to fit them to Parker and Parker Style ballpoint pens. Fisher also makes pressurized refills to fit Cross style pens. See the Fisher line by visiting our eBay store.
