Installation Procedures and Connection Dimensions
Safe, leak-free operation of any high pressure system depends on preparing and installing connections correctly. This page outlines proper instructions for the machining and assembly of BuTech L/P, M/P, and H/P connections. In addition, BuTech offers hand tools and power tools to make the preparation of the tubing easier.
Assembly Procedure
- Cut tubing to desired length and de-burr, allowing extra length for proper engagement. (see chart)
- Place gland nut and ferrule on tubing, making sure head of ferrule is toward gland nut. Push tubing into fitting until it bottoms.
- Screw gland nut into connection until finger-tight.
- Tighten gland nut approximately 1-1/4 turn with an open-end wrench.
Re-Assembly Procedure
- Insert tubing with gland nut and ferrule into fitting.
- Screw gland nut into connection until finger-tight.
- Tighten gland nut approximately 3/8 of a turn with an open-end wrench
High Pressure Connections
Assembly Procedure
- Slip gland nut onto tubing or nipple.
- Screw collar onto threaded end of tubing or nipple. Allow one or two threads to be exposed on tubing or nipple between collar and coned tubing.
- Lubricate male threads of gland nut with a non-hardening lubricant suitable for use on stainless steel. Lubricant chosen should also be compatible with working temperature requirements.
- Insert tubing into female connection of valve or fitting. Screw gland into connection until finger-tight.
- Tighten gland nut to torque value shown above which corresponds to connection size being assembled
