Nipple Builder™

Features
Half nipples are designed with a single flange, making them ideal for welding ports directly to chambers. On the other hand, full nipples feature a flange on both ends of the tube, allowing them to connect two components securely.
Adaptor nipples serve a different purpose, as they are used to connect two flanges of varying sizes or styles. The tube size typically matches the standard size of the smaller flange in these adaptors.
When measuring these parts, full and adaptor nipples are measured from flange face to flange face, while half nipples are measured from the flange face to the end of the tube.
The standard material used for these nipples is 304L stainless steel. Additionally, all tapped flanges are supplied with metric-threaded holes.

Tolerances
OAL | To |
0-600mm OAL | ± 0.5mm |
600-1500mm OAL | ± 1.0mm |
>1500mm OAL | ± 2.0mm |
Maximum overall length (OAL)
Maximum overall length cannot exceed 2000mm. Half nipples are measured from flange face to tube end. Full nipples are measured from flange face to flange face.
Minimum overall length (OAL)
The table below shows the recommended minimum length to allow for attaching mounting nuts after welding the nipple to a plate of the same thickness as the tube OD. Smaller lengths are possible by using bulkhead clamps (KF (QF) nipples) or threaded studs (CF nipples). Contact us for availability.
