Transitions

Transitions are swaged tubes that taper from a small diameter to a larger diameter. We make them with either 14° (Long taper) or 30° (Short Taper) included angles, and normally provide a 2" long straight section at the small end.

In the product listing here, the first number in the part number is the Small Dia. It is the outside diameter of the tubing the transition is made from, and the Max Big End is the largest diameter to which it can be swaged (the second number in the part number). The big end of your transition can be any diameter up to the Max Big End.

Short Transition

Long Transition

To order, pick your small diameter and a large diameter (not larger than the Max Big End), add the material of your choice, and specify either Short (S) or Long (L).

Example: RD-200-250-304 S is a short transition with a 2" small diameter, a 2 1/2" big end diameter, made from 304 stainless.

To determine the length of the tapered section, subtract the small diameter from the large diameter and multiply by 4.07 ( Long ) or 1.87 ( Short ). The straight section is normally 2" long.
