Lot includes qty. 2 union Tees, 1 elbow union, and 1 straight union. (I also have (2) 3/4" plugs in the lot, just to find them a home - they are used but perfectly good - or throw them away in not wanted.)
These fittings are orphans because their nuts and ferrules have been stolen, so if you have a supply of 3/4" Parker or Swagelok nuts and ferrules (or tubing that already has nuts and ferrules set), here's a screaming bargain. (...because I just hate to throw good stuff away!)
Is Parker CPI™ Really Interchangeable?
Yes. All threads, the seal seat angles and position, tube insertion depth, hex sizes and width, etc., are the same as Swagelok®. The fitting is totally the same as Swagelok® in all functional dimensions of the body and nut. The only basic difference between the two fittings is the fact that Swagelok® uses two ferrules while we use one.
