Indians For Guns

A few days back Malissa from Sun optics US, sent me the "O" rings to be fitted in the Benjamin hand pump.
Initially they told me that, they have no arrangement for credit card direct payment, rather I should pass on to them my credit card details and they will charge. Since it was quite an embarrassing situation I arranged remittance locally there.

They shipped and when I reported them after a month that, where is the package ? they promptly thanked me for my patience and brought me the good news that the package is lost in transit .

The consignment was sent again and this time I was lucky enough to get it.

I dis-assembled the pump and fitted a few rings, but to my surprise it only lasted for few days. Again I fitted a new set today, it took hardly 10 minutes for me, but I have observed the pumps need care at least once in every 2 months, without which rings will never last.

There are one very important O ring, which terminates most and I have to have a stock of that only in future.

By the way, I tried to manufacture here the Viton rings, and I was quoted Rs.30,000/- for the first set of 10 for each class including the dye, may be later recurring cost would have been nominal, but I dropped the idea as it crossed my head

Any way my Benjamin is again functional and I am a happy shooter again

If these information are useful to you, I am a happy guy.

Have you tried mcmaster carr...this is theory only (as I haven't ordered from there) but that is what I have heard some airgunners talk about. Try to get the o-rings that Tim @mac1airguns uses. My Qb has worn them for the last six or so years, without any wear. Just a slight lube with silicone grease is all the care that they have received.

Many thanks Dev !!

It's a fabulous website you have referred. I was not aware. Any way I have to explore the site for my other requirements too.
Let you know, if I get something interesting.
