  • Original Bellows Shaft Seal
  • 1 1/8 in. Bellows 2 1/4 in. to 2 3/4 in. stern tube
  • Clamp Ring assembly uses two clamps for maximum strength and proper balancing preventing galling or damage to the shaft that can occur with set screws
  • Seal ring is 316 stainless steel set in counter bore in the clamp ring assembly to ensure centering eliminating metal to metal contact and risk of electrolysis
  • To ensure the O ring is not damaged during installation it is clamped to the shaft after the assembly reaches its final location to prevent damage during installation
  • Hose barbs are constructed of solid brass and are coated to prevent corrosion
  • Hose clamps manufactured of 316 stainless steel indentations rather than perforations providing twice the tensile strength and eliminating friction as in regular hose clamps
  • Two hose clamps provided for each connection point
  • Specially balanced for smooth rotation the maintenance free original bellows features 316 grade stainless steel and special carbon graphite for its sealing surfaces of 3/4 in. to 4 in. in size
  • For larger sized shafts 4 1/8 in. to 8 in. they use 316 grade stainless steel an an oil impregnated nylon seal surface
  • The oil impregnated nylon has superior resistance to suspended solids such as sand and silt and is tough durable and won't crack or shatter
  • Like all Lasdrop models a cutlass bearing is incorporated in to the product to ensure correct alignment with the shaft
  • Because there is virtually no metal to metal contact you eliminate the risk of electrolysis
  • The Original Bellows seal will fit stern tubes 1 in. to 10 1/2 in. OD metric shaft sizes also available
  • Features a vibration absorbing bellows ideal for sail boats or workboats
