Vacuum Fittings - Weld Stubs and Rings

These are your basic flange fittings for connecting to stainless steel tubing to hard pipe various fittings or vacuum runs. There are standard sizes and there are specials. We will make these in whatever material you desire although our standard fittings come basically 304 stainless steel because of ability to weld. Aluminum gets more difficult to weld. We can make these in a variety of other materials including plastics and brass. There are various other methods to connect this stuff like brazing or connecting with PVC. For but welds you might
consider our 304 SS hose fittings although we can also make stub wedl flanges. For inside seated welds we have both weld cap fittings and socket weld fittings.

These items are packaged loose in baggies. Nothing fancy, but the price is right. Machined out of solid bar stock. Inside tolerances at size +.010" - 0.00".

I haven't had the time to back fill these prices so if you want to purchase and need the prices we have them all laid out for you in 2 different formats.
