Fittings — The cylinder fittings are made of corrosion resistant 316 stainless steel and now thread in to the cylinder via adjustable O-ring sealed ports. The fittings can be easily oriented in any direction to accommodate tube routing. Thread sealant is not required. Cylinders are shipped with SeaStar type hose fittings, if you require 3/8” SAE fittings, use the HF6003 fitting kit. Seals — Gland and piston seals have been updated and optimized for lower friction and longer life. Service Kits

Notes 1. HC5314-3 has the same bore and stroke as the obsolete cylinder, but a different mounting pattern. HC5319-3 has the same stroke and mounting pattern as the obsolete cylinder, but the larger bore will result in more system turns lock to lock. * The HC5314-3 uses a 1/2” rod end, if replacing a ram with a 5/8” rod end use HP6093 in addition. 2. HC5373-3 has same stroke and mounting pattern as the obsolete cylinder, but the larger bore will result in more system turns lock to lock. 3. The two new cylinders (HC5319-3, HC5373-3) are both designed for use in catamaran applications. Special “CAT” cylinders are no longer required. 4. All new cylinders use re-positionable ORB bleed tee fittings.
