SeaStar BayStar Cylinder Seal Kit HC4645H HC4648H HC4658H HP4600 FSM131-G2 Viton!! ( Generation 2 )FSM131-G2

This kit rebuilds the standard Sea Star steering Cylinder HC4645H HC4648H HC4658H, we used all Viton seals for this kit as Viton is a super material and costs 15 times more than other NBR or Urethane materials and last 2-3 times as long, Viton was Formulated by Dupont it is a Synthetic Rubber which resists Oxidation, UV Rays, Solvents, Acids and ozone on paper the working life of this material is about 30 years and I would suspect it will last even longer than that.  We have gone great lengths to bring better quality parts to the marine industry as we have seen these systems leak within 5 years of being new.  Low Quality Urethane Seals Deteriorate Rapidly In The Marine Environment  You won't find better seals on the market hands down.  These caps never wear out and they can be resealed without any issues.  We do not accept returns in order to ensure viability of our products; please be 100% certain of the application before purchase.
