## ~How 2-turn external Spirolox rings improve sealing and durability in connecting rod applications~
**A 2-turn external XWS series Spirolox Retaining Ring is used to clamp the rubber boot onto the groove in this connecting rod application. Since the ring provides a full 360° circumferential cover in the groove, a near perfect seal results when the boot is filled with grease. The ring and removal slots are also deburred to ensure the likelihood of the rubber being torn is eliminated.**
Our Smalley product, unlike a die stamped equivalent circlip, is produced by edge winding from a continuous coil of single filament pre-tempered round-edge flat wire and does not require heat treatment after forming. This unique process results in a retaining ring that has no ‘ears’ to interfere with the assembly and, because there is no scrap, they can be produced economically in carbon steel, stainless steel, coppers and many other alloys.
