PRE-ASSEMBLY TOOLS AND CONSIDERATIONS
Pre-assembly tools: These tools are manufactured from hardened Maraging Steel and are designed to withstand repeated assemblies. Pre-assembly tools can be used as an aid to make sure joints are correct.
Assembly tools must be kept clean and lubricated at all times.
Pre-assembly is recommended: Assembly can sometimes present difficulties, especially if the compression fittings are going to be used in confined spaces. Thick wall tubes or standpipe adaptors may also present problems. Pre-assembly ensures the fittings placement and installation to be correct.
Pre-assembly will reduce installation stresses when tube sizes exceed 1/2″ (12mm) OD .
Assembly Instructions: Ringlok Twin Ferrule Compression Fittings
Assembly Instructions for Ringlok Twin Ferrule Compression Fittings.
1. Cut the tube to the required length, leaving the ends square to the tube axis, remove all burrs.
2. Insert the prepared tube into the fitting assembly, ensuring the tube end fully enters the fitting, engages in the abutment diameter and that the nut is finger-tight.
3. For 1/16″, 1/8″, 3/16″ OD and 3mm, 4mm OD size fittings, tighten the nut 3/4 of a turn from finger-tight to complete the assembly.
All other sizes require use of 1 1/4 turns from finger-tight.
For blanking plugs, tighten the nut 1/6 of a turn from finger-tight.
Re-assembly: Ringlok fittings can be dissembled and reassembled many times without impairing the efficiency of the joints. Re-assembly instructions can be found here.
