with Auto Vent, Percussion Initiator Bottom Load
DESCRIPTION
The Coiled Tubing Pressure Activated Firing Head with Auto Vent was developed
for use where pressure firing is required such as in horizontal wells that will not
maintain pressure, in horizontal wells and for well stimulation. The Auto Vent
provides a method for venting the tubing at the time the firing head is activated.
It also provides the ability to see a pressure drop upon tool activation. This firing
head utilizes our precision shear pin technology with an accuracy of ± 5%. This
system can be set to activate at a predetermined pressure ranging from 2,000 to
12,000 psi in adjustable increments by using two sizes of precision shear pins.
FEATURES AND BENEFITS
• Can be used with the Owen Time Delay Fuses.
• Can be placed on top of all Owen Small Scalloped Gun Systems (1-11/16”,
2-1/8”, 2-1/2”)
• Well suited for highly deviated wells
• Minimum operating pressure 2,000 psi (13.8 MPa)
• Maximum operating pressure **12,000 psi (82.7 MPa)
• Requires pinning to 5,000 psi (55 MPa) to pass API RP-67 drop testing
• No metal to metal contact between Firing Head and Percussion Initiator
• The top thread connection is specified when ordering
** It is not recommended this tool be run above 12,000 psi (82.7 MPa) as
damage may occur.

Exploded View: TC-035-1688-000/100
Warning: The assembly of this tool requires the handling of an
6 I MAN-TC-035 (R00)
MAN-TC-035.indd 6
4/29/16 10:53 AM
Explosive Device and all safety precautions must be adhered to and
observed! Only personnel trained in explosive handling procedures
should be allowed to arm this assembly
Caution:
The shear pin values shown on the package
accompanying this tool are valid ONLY for the tools listed in this
manual
Caution:
Correct shear pin values will vary between lot dates,
always reference the data accompanying the pins!
Note: Check all items against the parts list to be sure of having the
correct parts and quantities.
Note: Check for any damage to the parts which would prevent the
part from being assembled correctly, easily and safely. Do attempt to
assemble the firing heading if any of the components require excessive
force to install. It is recommended to fit test the assembly of the firing head
without O-Rings to insure binding of moving parts does not occur. Replace
components if binding prevents parts from moving.
1.0 Assembly
1.1
Install the O-Ring (item 18 and 19) onto the Piston Housing (item 5). Set aside
1.2
Install the O-Rings (item 16) on the Shear Piston (part of item 7). Apply one drop of Loctite®
MAN-TC-035.indd 7
MAN-TC-035 (R00) I 7
4/29/16 10:53 AM
(use appropriate temperature rating) on the threads of the Firing Pin (item 6). Thread the firing
pin into the shear piston and tighten.
1.3
Slide the Outer Shear Ring (part of item #7) over the shear piston, matching the alignment
mark and numbers on the ring and piston. This will align the holes that were match drilled.
1.4
Install the O-Ring (item 17) on the groove of the Outer Shear Ring. With the tip of the shear
pin facing outward, insert the correct size and quantity of pins as per job requirements (refer
to the Pinning Procedures and Temp. Correction Chart in the back of the manual). Owen
recommends inserting the Shear Pins (items 9 and 10) as symmetrically as possible around
the outer shear ring. Starting with the large pins, first fill one (1) row before inserting pins in
the next rows.
8 I MAN-TC-035 (R00)
MAN-TC-035.indd 8
4/29/16 10:53 AM
1.5
After the correct number and size pins are inserted, you can apply a thin film of grease over
the pin tops and ring to help retain the pins during further assembly of this tool. Do not place
grease in holes of shear piston this makes it difficult removing the sheared off pin stubs from
piston. It is recommended installing the pins in a vertical position to prevent them from falling
out.
1.6
Apply grease to the O-rings on the shear piston (item 7) and the entry angle of the piston
housing (item 5). Insert the shear piston into the housing until the outer ring is flush with the
edge of the housing. Again it’s best to do this in a vertical position until the Venting Sub (item
8) can be threaded onto the piston housing. The venting sub is what retains the pins during
your operation. Install the O-Ring (item 20) on the top groove of the Outer Shear Ring.
1.7
Install the O-Rings (item 15) onto the Venting Piston (item 2), and thread the venting piston
into the top of the shear piston. Apply light grease to the O-Ring’s on the venting piston and
venting sub interior edge. The venting piston for the TC-035 tool has two groove marks on the
exterior. Install the venting sub over the venting piston and thread it onto the piston housing.
MAN-TC-035.indd 9
MAN-TC-035 (R00) I 9
4/29/16 10:53 AM
1.8
(These steps MUST be accomplished with NO DETONATOR in the detonator body.) Apply
light grease to the Retainer Cap (item 1) and O-Ring (item18). Remember, the retainer cap
comes blanked out and must be machine threaded to meet the particular thread requirements
of the tubular to be used. Apply grease to the threads and O-Rings on the piston housing
(item 5) and thread into the Detonator Housing (item 3) until both bodies are flush metal to
metal. Tighten with no more than 150 lb-ft (203 Nm) of torque. Install the two Set Screws
(item 11) into the upper end of the detonator body and tighten.

MAN-TC-035.indd 10
4/29/16 10:53 AM
Caution:
The next steps are only used prior to the well
operation. Never ship an assembled firing head with an explosive
component.
2.0 Detonator Installation
2.1
Remove the CP Detonator (item A) from its shipping package and install O-ring (item 14)
into the groove in the bottom of the CP detonator. Place the CP with O-Ring into the Retainer
Nut (item 4). Install the CP-Rubber Washer (item 12) on top of the CP detonator and inside
the lip of the retainer nut.
2.2
Thread in the retainer nut (item 4) assembly with CP detonator into the detonator body until
the lip of the retainer nut makes contact with internal surface of the detonator housing (item
3). Do not force retainer nut, if it is hard to thread, remove and check for cause. The retainer
nut uses a 3/8” Allen Wrench or the Hex Socket (TC-033-0010-000) to thread in. To secure,
use no more than 20 lb-ft (27 Nm) of torque. A torque wrench is recommended.
Note: To secure the retainer nut, use no more than 20 lb-ft (27 Nm)
MAN-TC-035.indd 11
MAN-TC-035 (R00) I 11
4/29/16 10:53 AM
of torque. A torque wrench is recommended. Caution: DO NOT use any
pointed device to install the Retainer Nut Assembly into the detonator
Body as it may cause detonation and serious injury.
2.3
Install the Top Sub Rubber Washer (item 13) inside the detonator body and up against the
retainer nut. This washer is used to prevent the retainer nut from backing off and as a debris
barrier.
Warning: The firing head assembly is now ARMED, and
caution must be used when handling and installing it on the main
well device! REMEMBER you are handling explosive components
so handle safely and do not over tighten any connections.
