FITTING ASSEMBLY GUIDELINES - stoneagetools.com

1 1 Understanding the proper preparation and ASSEMBLY of high pressure fittings and components is critical to the safe operation, maintenance and longevity of your tools and PIPE THREADST apered pipe threads (NPT) seal by contact of threads. A paste type anti-seize compound such as Parker thread -Mate along with pipe thread sealing tape works most effectively with NPT threads. Use anti-seize compound on male thread , then 2 3 wraps of Teflon tape (if larger than 3/4 NPT, use 3 4 wraps). Prepared fittings should engage about 2 turns by hand and at least 5 6 turns before reaching the recommended torque.

There are two pressure ranges for this type of connection: medium pressure up to 22,000 psi, and high pressure up to 40,000 psi. The traditional design consists of pressure containing tubing with a cone on one end and a left-hand thread for a collar, and a larger gland nut with right-hand threads.

9 FITTING sizes are indicated by tubing , an additional feature typically included, consists of a split tapered collet that grips the tubing in support to prevent cracking at the left-hand of these fittings are made where the entire geometry is reproduced in one piece, and where the tubing itself is directly threaded into a port with either left or right hand ports have a weep hole that will leak if the FITTING is not tightened, if the cone surface is damaged, or if the collar is not threaded on far enough to allow contact of the cone to the seat.

10 If a connection leaks along the tubing through the inside of the gland nut, inspect for a crack in the tubing and Collar Assemblies Inspect cone surface for damage. Use swagelok Blue Goop anti-seize on all male threads. Slide gland nut onto tubing, then thread on collar until one thread shows between collar and cone. Tighten medium pressure anti-vibe nut last while holding other Piece Connections Inspect cone surface for damage.
