Grand Prix Cylinders
Used as mast, sail, and keel controls, Harken’s highly efficient
Grand Prix cylinders outlast and outperform on the hottest
raceboats. They’ve endured hundreds of thousands of cycles in
the testing lab and have gone on to prove themselves on champion
TP52s and other winning Grand Prix yachts. Meticulous engineering
and top-quality components let Harken cylinders excel in constant
high-stress racing and harsh marine environments.
Cylinders are available in titanium or Hardkote-anodized, Teflon ® -
impregnated 7075-T6 aluminum for strength. Graphite-filled Teflon ®
rod seals and bronze-filled Teflon ® piston seals are extremely low
friction and are more durable than polyurethane seals. Performance
O-rings and slant springs in the seals provide consistent seal
pressure for a reliable, long-lasting fit. High-strength titanium,
17-4PH stainless steel, or Nitronic 50 rods and pins provide
superior strength and corrosion resistance.
Cylinders include a standard clevis jaw on both ends, but can also
be fitted with blocks and different eye types. Cylinders include push,
pull, and pull/pull styles.
