These animals are generally all “custom”. Some we stock some we do not. When you are considering a purchase on these please call us directly at 1-800-628-0850 and we will chat with you and get you a price quote and lead time. The Swagelok fittings we purchase so depend on others for lead times. We prep these up with certain machining characteristics and send them to our welder for assembly and welding and leak testing.
Pick Size desired and style to review pricing for the individual adapter. Weights and sizes are "variable" but in order for this store to work have been maximized to complete checkout and review. Slight differences will obviously apply here. These are all "custom" adapters and we can pretty much produce even more varieties. The best way is to decide what you want from the adapter is with information over at https://www.swagelok.com/en. This is the official site for these things. We just need a "tubing style", type, adapter to weld to our flange fitting to make any specific adapter fitting.
