Removing crimped hose from Medai pump
Here's one for the old-timers: I have a Medai pump, circa 1975. I'd like to replace the hose. The original hose is crimped onto the bottom of the pump.. First, how do I remove the crimp? Second, what is likely to be beneath it? I am hoping for a nib onto which I can attach a new hose with a hose clamp.
Thanks for your thoughts on this. BC pumped |

If your replacement hose has a different thread for the pump base, snip the band with a side cutter and use a stainless hose clamp. (some guys report a zip tie is sufficient but I prefer a hose clamp; under a dollar) -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Removing crimped hose from Medai pump
PITA what's the hose OD ? gotta vernier ? Amuzi has the position here like wahtizzit ?
I have a Wal barrel pump with crimped hose and a priceless locking hose end. hose cracked. epoxy plus banadae plus hose clamp after a search for unions failed ending in welding then refrigeration supplies for a fittable copper pipe. small diameters on the ID. Hwever life goes on....today maybe I'd remove the hose from its crimp leaving crimp intact then WEST 6500 epoxy a McMaster Carr union or fitting into crimp with an order for hose, hose end, and epoxy. Just finished similar for a Wal/Slime dc auto tire pump sold for cheap with a hose lacking....plasticizers sent over to where ? works n looks good in its Wal plastic cse with the fold over side pulls. Now in cargo above rear axle. |

The one I have is branded as a Raleigh. Looks absolutely identical to mine, which says Nashbar. I probably got mine in the mid-1990s. Mine came with a threaded hose end of some kind that screwed into the cast foot of the pump. I'm sure that Andrew is right, that you can cut it loose, then hose clamp a new hose in place. If you have trouble finding a hose clamp that small, there's a trick I used on a different frame pump, one of the ancient primitive ones with a hose that slides into the handle. Since I found no hose clamp that would allow the hose to slide in for storage, I just used many turns of fine wire to hold the hose onto its fitting. It's worked for a long, long time. - Frank Krygowski |

I might look over at Home Despot for a 3/16 hose barb and just splice the new hose onto it. Whatever is the least amount of work!

This somehow reminds me of tying and soldering spokes. BC |
