Identication of Metric DK-Lok Tube Fitting
Metric DK-Lok tube tting has stepped shoulder on body and nut
hex. Shaped tting such as tee, elbow, and cross forging has such
step on body as well.
Product Cleaning
Every DK-Lok tube tting is cleaned to remove surface contamination,
iron particles from cutting tools, oil from cutting uid, and loose particles.
For further information refer to DK cleaning standard DC-01.
Specialcleaning for oxygen service application is available on request.
Refer to specialcleaning standard DC-11.
Carbon Steel DK-Lok Tube Fittings
Carbon steel ttings are white zinc plated.
Every carbon steel tting is supplied with
SS316 back ferrule and Carbon Steel front
ferrule with black fast plated.
O-ring
DK-Lok tting pipe end with O-ring is supplied; 70 durometer NBR
O-ring on Brass and Carbon steel ttings, 90 durometer FKM O-ring
on Stainless steel tting.
Other O-ring is available on request.
DK-Lok Port Dimension
Dimensions on DK-Lok Port in the catalog are approximate gures
and shown in nger-tight position.
Alternative Fuels
Stainless steel316 DK-Lok Tube Fittings are tested to the requirements
of ECE R110, EIHP Draft, ECE R67 and certied by TUV.

All dimensions are in millimeters unless otherwise specied and only for reference subject to change.
Tubing
For safe, reliable and leak-free DK-Lok tting
system, tubing should be considered as one
of tting components.
t Tubing is assembled by simple wrench
make-up on DK-Lok fitting. This results in
less assembly and maintenance costs.
tTubing assembly on DK-Lok fitting is re-usable.
t Tubing is bendable. It allows lower pressure drop with fewer
connections. This in turn reduces system costs because of less
fabricating manpower.
t Pipe threading or welding is difficult to disassemble and
re-assemble
t Piping requires skilled worker for welding & threading
DK-Lok Tube Fitting Pressure Rating
t The pressure rating of DK-Lok Tube Fitting is rated to the working
pressure of connective tubing.
t The allowable working pressure of tubing in various materials is
listed in the table 2 to 13.
Material
Using like tubing and tting materialis essential for leak-free sealing
Material
system.
Unlike material may have dierent mechanical properties that may adversely aect the tting seal on tubing.
The only exception is copper tubing with brass DK-Lok tting.
Tubing Selection
Hardness
t Tubing must be softer than fitting material. The metal tubing
must be fully annealed and suitable for bending and flaring.
t Tubing hardness must be selected according to the information
in the table 2 to 13.
Surface
t Tubing must have a surface free from scratches, draw mark, dirt,
dust and flat spots.
Ovality
t Tubing in oval or out-of-roundness way not fit into the fitting.
Do not force the tubing into the fitting; it may damage the fitting
sealing system on nut, ferrules, and body.
Wallthickness
t The table 2 to 13 list tubing working pressure ratings in a wide
range of wall thickness. A too thin wall may collapse and a too
thick wall may not properly be deformed by the ferrule action.
t Do not use tubing wall thickness not listed in the table 2 to 13.
Weld tubing
t Welded tubing should have a not measurable bead on its outside
diameter.
Tubing Handling
Careful handling and storage practices will protect tubing from
unnecessary scratches, nicks, or degrading the good tubing surface
nish.
t Tubing ends should be capped so any foreign materials will not
fall inside during transportation and storage.
t Do not drag across tubing rack, cement, gravel or any rough
surface.
t Do use correct tube cutter for tube material. The wrong cutter
may result in excessive deformation of the tube end.
t Do not cut deep with each turn of cutting.
tTube cutters and hacksaws should be sharp enough.
tHacksaw blades should have at least 32 teeth per inch.
tDo deburr tube ends before inserting in fittings.
Gas Application
DK-Lok tube tting is designed for a wide range of leak-free application
including gas leak proof and vacuum tight service.
Gases (helium, hydrogen, nitrogen, air, etc.) can escape even the most
minute leak-path due to their very small molecules.
Tube therefore must be handled not to have scratches, draw mark,
nicks, at spots, dirt, and dust
Use NOT thin wall tubing for gas applications.
Heavier wall tubing resists the ferrule action whereas thin walltubing
may collapse with little resistance to ferrule action.
For Gas service, use the tubing wall listed on un-shadowed section in
table 2 to 13.
Vacuum Application
DK-Lok Tube Fittings have been proved to be excellent vacuum tight
seal in many applications including analytical industry.
DK-Lok Tube Fittings comply with the leakage requirements of TA-LUFT
2002.
Cryogenic Application
DK-Lok Fittings in SS316 Stainless Steel provide highly reliable
performance on cryogenic application.
Cryogenic temperature is considered to be temperatures below
-100℉ (-73℃).
High Pressure Application
Pressure 500 psig (34.5 bar) or higher is considered generally high
pressure. In the high pressure system scratches, draw mark, nicks,
at spots, and dirt on tubing may cause leakage
t For gas application, select the gas applicable tubing wall
thickness from Table 2 to 13.
t Follow the suggestion on tubing selection, handling, and
installation.
All dimensions are in millimeters unless otherwise specied and only for reference subject to change.

Weld Stainless Steel Tubing Allowable Working Pressure
To determine the working pressure of weld tubing to the requirements of ASME B31.3 Code, de-rating factors below must be applied. For single
weld tubing multiply by 0.80, and for double weld tubing multiply by 0.85:
Example: SS316 seamless 1/2 in. O.D. x 0.065 in. WT allowable working pressure: 4700 psi.

To determine the work pressure of the single weld tubing, multiply 4700 psi by 0.80.
4700 psig x 0.80 = 3760 psig at -20 to 100℉ (-28 to 37℃).

Temperature De-rating Factors
The pressure rating of DK-Lok port is governed by the connective tubing pressure rating.
To determine allowable working pressure at elevated temperature, multiply working pressure by applicable factor shown in table 14.
Example: SS316 seamless tubing 1/2 in. O.D. x 0.065 in.WT at 700 °F. 4700 psig x 0.82 = 3854 psi.
Allowable working pressure of SS316 seamless 1/2 in. O.D. x 0.065 in. WT is 3854 psi at 700 °F.

Pipe Thread Sealants
Pipe thread sealant for tapered pipe thread assembly is essential to
ensure leak-free thread sealing. Sealant usually contains a lubricant.
Thread sealant lls the voids between the threads and prevents
thread galling.
Wrap PTFE tape clockwise from rst thread. Do not overhang the rst
thread; the tape may get into the uid system.

Thermocouple Connector
DMCT
23
Most DK-Lok male connectors can be bored-through thermocouple ttings except
those ttings with small male thread like 1/8 in.
To order, insert T in DMC male connector part number. Example: DMCT8-8N-S
DK-Lok bored-through ttings have no shoulder or sizing angle inside the body. This
allows thermocouples or dip tubes to pass beyond the tting male thread.
Assembly instruction
1. Position the length of thermocouple to pass through tting male thread and hold
it to prevent shifting during assembly.
2. Wrench tightens the nut 1 1/4 turns from nger tight position, keeping the body
steady with backup wrench.
•Tighten the nut 3/4 turn for 1/8, and 3/16; 3, and 4mm Tube Fittings.
All dimensions are in millimeters unless otherwise specied and only for reference subject to change.
