Pusher seals are usd with pusher type tensioners. pushing against the seal tensions the strap. These are recommended for bundling rods and tubes and for coil strapping. Also known as “Overlap seals”.

Thread-On may used with all tools except pusher type and magazine fed tensioners. Pro- threaded on the overlapping strap ends before the strap is tensioned, they are excellent for use on narrow operating surfaces, on vales of bundles, of where it is desirable to form a loop with the seal holding the strap.
