I recently acquired a Parker 21 that is missing its sac.  The metal aerometric shell is in place, just no sac.  I would like to replace it myself but can't find any info here or on YouTube about putting in a replacement sac for a Parker 21.

 

My experience level-I have extensive knowledge of 45s but little on older pens with sacs.  I have replaced the cracked hood on another 21 I bought. I have watched Danny Fudge replace several sacs on Esterbrook Js.

 

My questions:

1) Are there any videos or guides for replacing the sac on a Parker 21?

2) Will I need to remove the hood to remove the aerometric filler?

3) Do 21s have a breather tube? (I don't see one on mine)

 

Thanks for any suggestions and advice.

Replacing the sac on a 21 is the same as replacing the sac on a 51.  You have to pull the sac guard off to get to the sac.  The originals were PVC.  David Nishimura's 51 sacs are PVC, and should fit the 21.

 

The 21 typically has a short(er) plastic breather tube, not the long metal one of the 51 aerometric.

Thanks Ron. 

Will I be able to remove the sac guard without removing the hood?

Is the breather tube essential?  If so, any suggestions on finding one?

 

Thanks again,

Cabbie
