Air Arms Commercial site aselkon

Hello everyone,
I've recently acquired an Aselkon Ravello RX5 air rifle in 5.5 calibre from a gunsmith here in Morocco, but he doesn’t seem very familiar with this model. I noticed there was an excess of oil inside, and the rifle loses air after a few hours. After disassembling it, it appears the issue is due to a faulty O-ring that hisses, rather like a punctured tyre.

Being based in Morocco, I’m limited to ordering replacement parts online. If anyone could kindly point me to a website where I could purchase suitable O-rings and, if possible, an optional regulator, I’d be most grateful.

Many thanks in advance for any help and advice!
 
Thank you so much for your help. I placed two orders for the O-rings on the site you mentioned, but they informed me that they don’t have a regulator!
Given that I have limited technical knowledge, I’m not sure whether I need a specific regulator for the Ravello RX5 model or one that meets a particular standard? My goal is to regulate the shots to the maximum power of my rifle, which is 52 joules.

I had an Aselkon Ravello RX6 that I used for about a year before it started leaking. I contacted many airgun suppliers and found no support from any of them. I had it apart 4 or 5 times trying to figure out the leak and eventually figured it must be the regulator that was leaking. I tried to order one and was never able to. So I gave up and sold it.
I wish you good luck in your endeavor.
