Harwood’s 12H Series high pressure fittings and tubing have a maximum working pressure range from 180,000 psi (12H-2) to 200,000 psi (12H-1). 12H-1 is our most common type of fitting. It uses rigid tubing and a metal on metal cone seal. 12H Series high pressure fittings are good for large volume pressure work at 200,000 psi.
Information for 12H Series crosses, tees, and elbows are given below. See the high pressure tubing page for details on Harwood’s 12H Series tubing.
