I found this link and thought it may be useful to others. It’s all different types of hose fittings. It beats driving around to 5 different hardware stores to find all the fittings you may need.
If you still can not find what you want from above site, maybe you can consider following site: www.better-fitting,com:D
If you guys can not find fitting from above address, please check www.better-fitting.com for metal fittings.
