YES, this converter will work with most pilot fountain pens including pilot parallel and decimo. The only thing that I don't like, since the front body part of parallel is semi-transparent, the ink will stuck in there after you dip the nib into ink. It's kind of annoyed me. The BEST solution and probably cheaper solution is Private Reserve Cartridge filling units (24CAR). You can refill any ink cartridge with any bottled ink. For parallel, you still have that small ball inside the cartridge to stir the ink and it hold much more ink than this converter too.
For other pilot fountain pens, this converter works wonder.

I have one of these and they DO NOT work with he Pilot Cavalier fountain pens. You can install them on the Cavalier but then you cannot close the cap because the pen is thinner than this converter. The converter itself works well just be careful what you are installing it on.

At first, I thought the Con-50 would not hold much ink because of its unique design - the plunger does not go past the first half inch of the barrel. This means you have to suck up and purge ink through the pen a few times to completely fill the converter. Overall, not a bad investment if you want to move into the wonderful world of bottled FP ink!

I would like to re-review this item and up the stars ^_^;;...after a few tries, it's working great now. I find it easier using a dropper to fill the converter and then inserting back into my pilot pen.

I'm using the CON-50 with my Pilot Duo and a Pilot 77 Muyrex, works like a dream, fits well, no leaks. I love it. Personally I prefer it over the Con 20 with the Sac refill. Not sure what the issue with Cavalliers is, but I think my Duo has the same physical dimensions and works great.

I found that this converter had a bit of trouble getting suction when installed on a pen that has never had cartridge ink run through it. I eventually got it to fill about 1/4 of the way, then wrote for a while, which apparently gave the ink a chance to distribute through the fins in the feed tube (visible through the barrel of the clear body Penmanship), after which it could be filled at least 3/4 of the way with Noodlers' standard ink.

I have a converter for my Lamy which works wonderfully. I purchased this Pilot Converter to go with the Pilot Penmanship Fountain Pen. They do not work well together and gave me so many problems and spillage.

A well-made and reliable converter that fits perfectly in many Pilot pens. The only downsides are that it is on the small side for ink capacity, and it is a bit expensive.

This fits both my pilot penmanship and pilot plumix perfectly. With this, I can just refill my pens without buying cartridges.

So far I've used this with no trouble. My only gripe is that it's quite small compared to other converters. However the suction of the piston is very good and fits securely into my Pilot Metropolitan pen. I would recommend this for that pen if you're not a fan of the squeeze converter that it comes with.

The Con-50 converter does fit in the Pilot Cavalier Duo-Body, a fountain pen which is slighter wider than the Cavalier.

I purchased this converter for my Pilot Decimo. The CON-50 converter fits great, and it doesn't leak or anything, but I'm having trouble getting the converter to fill up with ink all the way. I've been dipping the pen nib into the ink and using the converter to pull up the ink thru the nib, but despite pulling the plunger back and then forward to try to get the last little bit of air out, there's a space in the clear section of the converter that I can't manage to fill with ink. So, I'm giving this a halfway decent review because the space in the converter means that I have to refill it more frequently.

Also, I have a Pilot Cavalier fountain pen, and this converter DOES NOT FIT WITH THE PEN BODY SHUT, as mentioned by a previous reviewer. It would be ideal if this were just a little bit less wide, because I have a love-hate relationship with the CON-20 (with the balloon/sack). To be clear, this converter fits in the nib part, but you can't close the pen body with this converter.

I have no problem with this converter. I strongly suggest following the instructions on using converters following the link above.

The way I fill my converters is to remove them from the pen, and hold the end of the converter into the ink while I unscrew the piston. That saves ink and makes for a lot less mess. However, I found that unlike other converters I've used, this converter doesn't narrow down at the tip, so if you turn it upside down with ink in it, the ink runs out in a gush! Still it works fine with my Prera.

Would this converter work in a Pilot Parallel Calligraphy pen?
The "converter" that comes in the package works for cleaning the pen, but not
for ink refills.

Love the Pilot Parallel. Awesome pen.

I purchased this for use with my Pilot Plumix fountain pen, but I believe it is compatible with a wide range of other Pilot products as well. It's shaped like and installed in place of a regular Pilot cartridge. Use is pretty intuitive; press and hold the button on the side, submerge the entire nib in ink, then release to draw ink up into the converter. (You might need to repeat a couple of times to make sure most of the ink is going into the converter and not the feed.) I fill directly from the ink bottle and it works perfectly, no spills or splatter! I also think it holds a bit more ink than the CON-50, although unfortunately the CON-20 is not clear so you can't see how much is left. A good, cheap choice for those who want to broaden their ink and color options.

Works well with the Pilot Cavalier sold here. The converter already contains an inner sac so all you gotta do is attach is and you are good to go. Don't need anything else except an Inkwell to fill your fountain pen from.

This leaked with both my Penmanship and my Plumix from Day 1. I've read that they are inconsistent in quality and that leaking is often a problem. Very frustrating.

I really don't want to use cartridges, so I'm ordering a CON-50. But I would have preferred not to waste money on the CON-20.

I use this converter with the Pilot Plumix. It works great, construction is pretty good for the price.

I don't know how they could say this is compatible with the Pilot Penmanship, it's too lose at the section, it can't even fit! I purchase this for the price $3.3 and was so disappointed, cause I love the Penmanship too much, not just for the price but also for the quality, the extra fine line is so good for me that I couldn't find anywhere! I've planned to buy the cartridge, but I love the Turquoise ink and they didn't appear as cartridge so I have to buy those converter. I hope the CON-50 would be better but I think it's not worth to buy the converter the same price as the pen!

I just received my penmanship fountain pens with the ergonomic grips and the extra fine nibs. I have been using fountain pens for over forty years and was extremely impressed with how incredibly fine the nib was while still writing so smoothly. The only problem I encountered is the lack of a pocket clip. But for the price, I guess I can't complain.

It was horrible. It worked for the first refill, but leaked everywhere from then on. I have wasted so much time and ink with this peice of crap.

Please please restock if you can. The converter has not been available since I purchased my Cavalier which is in a red hot tie as my new favourite fountain pen. I am stuck with BORING blue cartridges until I can get my hands on the converter!

i wonder if this will work for Platinum preppy pens ???
ohh please please restock :)))
