Ferulok Assembly
Ferulok fitting assembly consists of the following steps:
1) Cutting, deburring and cleaning of the tube
2) Ferrule pre-set
3) Pre-set inspection
4) Installation
Step 1 (cutting, deburring and cleaning of the tube) has been
previously covered (see page T12).
For the recommended minimum and maximum tube wall thick-
ness for Ferulok fittings, please refer to Table D2 on page D5.
Ferrule Pre-set
Prior to final installation, the Ferulok fitting requires a pre-setting
operation that creates a bite by the ferrule into the outer surface
of the tubing. Pre-setting can be accomplished by two different
methods: hydraulically using a Hyferset Tool or a Hydra-Tool, or
manually using a hardened Ferulset tool or the fitting body.
Prior to pre-setting, determine the tube length allowance “A”
using Table T22.
Pre-setting using Ferulset Tool or Fitting Body
*No additional lubrication is required with stainless steel fittings as the nuts are
pre-lubricated.

ance
Step 1 – Lubricate thread
and cone of Ferulset Tool
(or fitting body).
Step 2 – Slip nut and ferrule
over deburred tube end. Be
sure the long, straight end of
the ferrule points toward tube
end.
Step 3 – Lubricate ferrule with
system fluid or a compatible
lubricant.
Step 4 – Bottom tube end
firmly on internal shoulder of
Ferulset Tool (or fitting body).
Step 5 – Manually screw nut
onto Ferulset Tool or fitting
body until finger tight.
Step 6 – Make reference
mark on nut and tube.
Step 7 – Hold tube steady
against internal shoulder of
Ferulset Tool or fitting body
and tighten nut an additional
1-3/4 turns.
Step 8 – Loosen nut and
check for proper pre-set.
Use the following inspection
criteria.
Ferulset pre-setting tools made from hardened steel are
available for sizes 2 through 32. (See page S38.)They are
recommended over the fitting body because they can be used
repeatedly to perform the pre-set operation.The fitting body can
be used only once for pre-setting and should be used during
final installation with the pre-set tube line. The following steps
are required for proper pre-set of the ferrule using the Ferulset
tool or fitting body.
