In the past there has been a history of safety concerns surrounding the misidentification and inadvertent mismatching of 2″ Figure 602 hammer unions with 2″ Figure 1502 hammer unions. When a 2″ Figure 602 female sub is screwed into a 2″ 1502 nut, the combination may hold pressure for a short time but it will ultimately fail. Unfortunately this mistake has caused property damage and injuries in the past.
In an effort to prevent this from occurring in the future, many industry leading manufacturers, including C&C Industries, have adopted a new design for the 2″ Figure 602 female sub. This design will not allow the 2″ Figure 602 female to be made up to the 2″ Figure 1502 nut. If an end user tries to mate the two hammer unions, they will immediately notice that the threads on the female sub do not engage the threads on the nut.
Careful attention was taken to ensure that the new design is reverse compatible. The male sub and nut of the 2″ Figure 602 Hammer Union have not been altered in any way, so if there are old parts in your inventory or in the field, they will still mate up with the new female sub if necessary.
You may notice that the hammer union looks visually different, particularly that the acme threads on the female sub may remain partially exposed even when the hammer union is fully hammered together. However, this is normal, and does not affect the sealing properties of the hammer union in any way.
We appreciate your continued support of C & C products, and as always, we will be happy to address any comments or concerns you may have about this change.
