Good Evening, I have a plastic seal that fits over lpg cylinder valves here in Jamaica. I'm not able to find anywhere that actually has the seals so I branded it would have to be made. My client only has a used sample of it as only one other company here uses it. I have some pictures of what it looks like. If you can give me an address to send it to you then I will do so. I do not have specifications on it but the picture. The material is plastic. Show More
