We have now added a PTFE coated version of our incredibly popular QC Ring Swivels, which is designed to ensure that they spin even more freely. Polytetrafluoroethylene (PTFE) has one of the lowest friction coefficients of any solid material, which makes it perfect for coating swivels as it reduces any friction between the barrel and the eye, and the freer spinning they are, the less chance there is of tangles, plus can make some rigs more efficient as well when it comes to hooking fish. They feature the usual quick-change connection, which has become very popular and just needs covering with an anti-tangle sleeve. They come in a choice of size 8 or 11, and there are eight in a pack.
