B3776E Housing for Platinum 3776 Nib and Feed

Description

B3776E Bock #6 housing allows use of a Platinum 3776 nib and feed into Conid fountain pens that use Bock #6 nibs.

Manufactured in the USA by Flexible Nib Factory LLC from black ebonite from Nikko (Japan).

Platinum 3776 nib and feed not included.

Does not fit the Platinum 3776 music nib. Please see B3776EM instead.

Below, see the difference between the old style Platinum 3776 nib (left) and the new style (right). The B3776E fits the new style, and the B3776AE fits the old style.

 

Note that there are some dimensional differences in some Platinum 3776 nibs and feeds related to the internal diameter of various versions of the Platinum 3776 pen’s section. This housing has a 0.260″ internal diameter. If your nib and feed are loose when installed into this housing, please contact us for a version with 0.258″ internal diameter (we will exchange for free). Also, make sure you have the new style (above) if you are using the B3776E housing.

Installation Instructions

Remove the feed and nib from your Platinum 3776 pen:

• Empty your pen of ink in your usual way and rinse out the residue.
• Before removing the nib and feed, note the position of the nib in the section. You will want to have the nib and feed fit similarly in the B3776E housing.
• Grasp the nib and feed, at the base only, keeping your fingers off the tines and tip of the nib, and pull them straight out of the pen. If the nib and feed can’t be easily removed, soak the nib and feed in a dilute household ammonia solution for a few hours, and this should allow you to remove the nib and feed from the housing. As a last resort, the nib and feed can be removed using a nib block and punch, but this method should not be necessary unless the pen has been allowed to dry with ink inside.

Here is a wonderful video by the great YouTuber sbrebrown (no relation to Flexible Nib Factory LLC) on disassembly of a Platinum 3776 pen. The removal of nib and feed start at 1:49 into the video. Normally, I have found it doesn’t take much force to remove it, and on the two pens loaned to me, I was able to easily remove and replace the nibs with my bare fingers. The most important point is to not twist as you pull, and KEEP YOUR FINGERS OFF THE TIP AND TINES.

To install the Platinum 3776 nib and feed into the B3776E housing:

• Place the Platinum 3776 nib on the feed so it fits securely and snugly.
• Without twisting, and keeping your fingers only on the base of the nib and feed, insert the nib and feed fully into the housing. The markings on the nib should be aligned as they were when the nib and feed were installed into your Platinum 3776 pen’s section.

Here’s another video from sbrebrown about the Conid Bulkfiller cleaning, which shows how to remove and reinstall the nib unit, starting at 1:46. Install your B3776E with Platinum 3776 nib and feed exactly as shown in the video.

Here are photos of the B3776E housing with the Platinum 3776 nib and feed properly installed. As always, please contact us if you have difficulty.
