6.1. Wiper Dart, Chevron Shape (Green & Orange)
|
|
|
We make darts of PU Foam Sponge, as the cylindrical sort, but shaped
similarly to a wiper dart, the aim being to enable such a dart to act
as a wiper while being flexible and extrudable enough to pass through
a restriction. They are effectively softer and can be used to leave
a film of eg anti-rust treatment on tubing.
|
|
|
The basic versions are now listed here, but special designs have been
made. The extreme of this has been a dart with the ability to wipe a
2 7/8" tube, but pass a restriction and then wipe a 2" tube. All
such are job-specific and designed and made accordingly.
