Does anyone know a source for leather pump cups for duraseal pumps? I only have 2 left from my old stock, and can’t find a current source
I have emailed MSR. The Arctic pump includes a leather cup, although no parts are listed on their website. I have asked to buy some . MSR only sells parts in kits, from past experience. Expensive, and inefficient for stove herd owners like me. There was a supplier of pump cups from Japan, on eBay, from which I acquired leather pump cups far superior to the rubber ones MSR uses now. I have emailed them, as they no longer list a leather cup specifically for MSR pumps. A leather cup of the correct diameter should work, provided the hole is not too big. I will post the results of my quest here. MSR, pay attention to your customers needs!
@xgk281 , Welcome to CCS! You might consider contacting our dear friend, and fellow CCS member @sefaudi , to see if he makes a leather pump bucket for the MSR pumps. Sefa's pump leathers are as good as they come, and MUCH better than most of what you might find out there. Good luck, and God Bless! Every Good Wish, Doc
Are leather cups really better than rubber? Not saying they're not, but it seems counterintuitive. What is everybody's experience?
Long term I think leather is best. I've never worn out a leather I've replaced & have rejuvenated many that are decades old.
You just have to keep them from drying out, right? I wonder if it's because leather is inherently fibrous, so as long as you keep them from drying out, they are much more resistant to tearing and abrasion.
I absolutely prefer leather to plastic, or rubber! They are strong, exceedingly long lasting, and work a treat! For what it's worth....
Hi PW, Leather cups are durable and rarely wear out. They can be revived, and are very reliable. They can be revived without needing a replacement part, which is a big advantage in remote settings. I have nearly finished converting my Duraseal pumps to leather cups. I noticed several which had cracked edges, which were getting ready to fail. After only a few years of use , some after only 1 year. Msr parts kits usually only have one spare. Use that spare to fix a failed rubber cup, and you no longer have a spare for the rest of your trip. Not recommended! Parts kits are expensive, and buying rubber pump cups individually is not something MSR advertises on their website. Earlier versions of pumps used leather. One of the experts here has written about this here somewhere. and, a leather cup can be manufactured with a piece of leather in camp, as others have described. Just the kind of options one needs in the bush. MSR uses a leather cup in their Arctic pump for reliability in the cold.I usually have a spare leather cup in my kit, and a rubber one for back up.
Convinced! Ya learn sumpthin new every day... Checking with @sefaudi to see if I can get one for my MSR. Thanks - Paul
When a non-leather pump cup fails, it's often all at once. It won't hold pressure, and you'll find it has ripped. Leather rarely does that, and even a dry and ragged leather cup can often be revived in the field by rubbing oil into it. ....Arch
Sefaudii has replied to my email. He doesn’t make Msr pump cups, as he has never had one. He thinks an Optimus Nova cup might work but needs some some dimensions. I am away until this evening and can’t go measure my pump until then. Does anyone here own a Nova and a Msr duraseal pump, who can check compatibility? Sefaudii needs to know: Pump tube inner diameter Height Hole diameter Do any MSR gurus have these dimensions handy?
@xgk281 , Just a thought, but why don't you measure the spare pump cup that you have from MSR, and send that measurement to @sefaudi, in the interest of expedience? If that won't work for you, and you're not in a hurry, I can make the measurements you need, next week. Up to my neck in work, right now. Take care, and God Bless! - Doc
As Ken suggested, I think making your own is the way to go. Once I figured it out with help from various other folks, is quick and simple.
