We have added internal stops to all Centerfire™ and Quik Tip™ Diffusers to improve alignment between the liner and contact tip for enhanced wire feedability.
This product improvement is being implemented as a running change.
The new internal stop inside Centerfire and Quik Tip Diffusers prevents the liner from going all the way through the diffuser, therefore changing how liners need to be installed. Liner installation will now require the removal of the diffuser.
Please note that trim lengths will also be affected.
See Insert INS-DIFF for more information.
How can I tell the difference between Centerfire and Quik Tip Diffusers with the NEW internal stop vs. the original style Centerfire and Quik Tip Diffusers?
To help distinguish Centerfire Diffusers (shown below, left) with the new internal stop, users can check the orientation of the roll mark. In original style diffusers, the roll mark is readable when the tip end is at the top. In diffusers with the new internal stop, the roll mark is readable when the neck end is at the top.
Quik Tip Diffusers
To distinguish Quik Tip Diffusers (shown above, right) with the new internal stop, users can check the roll mark. In the original style diffusers, the roll mark has one Bernard starburst stamped before the part number. In diffusers with the new internal stop, the roll mark has a Bernard starburst stamped before AND after the part number.
For both Centerfire and Quik Tip Diffusers, a second simple method to check for an internal stop would be to insert a liner into the diffuser. If the liner will not pass all the way through the diffuser, then an internal stop is present.
Please note that it is important to understand which diffuser you are using as this affects liner trim length during replacement. Please refer to the insert inside of your diffuser bag or click here for additional information about liner replacement and trim length details.
