SKF Muff Coupler Wrap – Huge Shrink Sleeve

SKF Steel Muff Couplers need to be sealed from sea water with shrink sleeves

SKF OKC Hydraulic Muff Couplers come in steel and stainless steel versions.  The majority that we come across are steel even though they are submersed in salt water.   Older installations attempted to keep the water out by wrapping the coupler in fiberglass.

SKF developed a shrink sleeve for each of the coupler sizes.  This  sleeve wraps tightly around the coupler and shaft and seals the part water-tight.   This shrink sleeve process was completed in less than a half hour using a large propane torch.  Thanks to our friends at South Cross Boat Works (another LMC Lauderdale Marine Center on-site contractor that specializes in shrink wrapping and scaffolding) that use large propane torches for shrink wrapping boats.  It is nice to use the right tools for the job.  

 

This is the finishing touch on completing the 131′ Feadship project.
