Catalog Features a Variety of Tube Fittings


Information on Mark VIII O-SEAL Tube Fittings from CPV Manufacturing is available in a comprehensive 20-page catalog. These fittings have established leak-proof reliability for “dry-machine” applications to 6,000 psi, according to CPV. Connections can be secured, even with low-torque, hand tightening.  Plus, they offer “slip-in/slip-out” accessibility and do not shake loose under vibration. Internal line pressure increases the sealing effectiveness of these fittings. 

The Mark VIII fittings are available in stainless-steel and other alloys such as bronze, Monel and titanium. Unions and connectors come in a variety of useful configurations as well as sizes from 2 inches to one-eighth-inch O.D.
