I'm trying to find all the seals to repair an AN6201-1 hand pump. I've managed to order all of them excelpt MS28775-21Z. What is this part number? I can't find anything on it. Is it just an MS28775-21? Thanks! |

Hi Kevin, It could be an MS28775-212 which is a thicker o-ring than say an MS28775-21. David |

David, You might be right, however, it's a typed document. https://wwwproc.redstone.army.mil/acquisition/padds/web/W58RGZ06R0421/attach_exhib/B-1%20Manual.pdf I'm sure it's Z and not a 2. However, can anyone verify? Maybe there's a typo here? Page 21 of the document, page 36 of the file... Part 5-52 Thanks.. |

David, you are absolutely right. I found a different copy of this TM and while the parts list also indicated 21Z, a supplement listing of repair parts to have on hand lists it as 212. http://www.scribd.com/doc/32049806/B-1-Stand-Manual Thanks for the suggestion, made me dig deeper... KK |

If you haven't found it, I have used http://o-rings.com. They are reasonable, and they will package your stuff for 10 year shelf life. |
