5. Check to make sure the gasket faces of the assembly are
flat by placing a straight edge across the face. If faces are
not flat, holder is not suitable for use (See Figure 3).
Figure 3 - Measuring for Flatness
6. If necessary, clean the seat area with a solvent that is
compatible with your media. If this does not remove dirt,
hand polish the seat area with Scotch Brite fine emery
cloth or #0000 steel wool. D N T MACHINE THE
RUPTURE DISC H LDER! If scratches, nicks, corrosion,
or deposits cannot be removed by hand, contact the
factory.
ASSEMBLY
WARNING: Before attempting to assemble the rupture disc
and rupture disc holder, confirm that the seat area of the
rupture disc is designed to fit the rupture disc holder.
1. Place holder component with female seat on a work
surface (See Figures 4, 5, & 6).
Figure 4 - Insert Holder
2. If the holder was supplied with an optional o-ring groove,
install an o-ring into the groove of the component with the
female seat. Note: Use of an o-ring is for improved sealing
and is not required for proper function of the rupture disc
assembly. Do not install an o-ring unless the holder is
designed to accept these components by Fike!
3. Place rupture disc into holder component with female seat
with flow arrow on tag pointing in the same direction as
holder component with female seat flow arrow.
DiscLoc
TM
tab, if present, must seat properly in recess.
4. If the holder was supplied with an optional o-ring groove,
install an o-ring into the groove of the component with the
male seat. Note: Use of an o-ring is for improved sealing
and is not required for proper function of the rupture disc
assembly. Do not install an o-ring unless the holder is
designed to accept these components by Fike!
5. Carefully align and place holder component with male seat
onto rupture disc with flow arrow in the same direction as
disc and holder component with female seat flow arrows.
CAUTION: Be careful to not allow the male seat
component to strike or damage the dome of the rupture
disc!
Figure 5 – Alignment pin fitting in tag slot. (ATLAS sizes
14” and larger”)
WARNING: For ATLAS sizes 14” and larger, ensure that
the alignment pin in the holddown fits into the tag slot of
base (see Figure 5) and check the gap (see Figure 7).
Fragmentation or leaking can occur if this feature is not
aligned properly.
6. Rotate component with male seat to align sideclip holes.
7. If holder configuration is Insert, install sideclips and tighten
securely.
8. If holder configuration is TQ, turn assembly over to access
capscrew holes (depending on design).
Note: It may be beneficial to move/tilt or support the
holder to first install a few capscrews evenly around the
perimeter before turning the assembly over.
9. If holder configuration is TQ or TQ+, lubricate uncoated
capscrews with a light oil such as SAE grade 20. Lubricate
both the threads and the underside of the head. Install
lubricated capscrews and tighten until recessed and snug
in the holder (see Figure 6).

(TQ+ configuration s own)
10. Check gap between base and holddown. The gap must be
the same size on all sides of the assembly. This can be
assured by measuring the distance between the holddown
and base at various places around the circumference of
the assembly. Adjust pre-assembly screws if necessary to
provide an even gap (See Figure 7).
Figure 7 - Gap Inspection
11. If holder configuration is TQ or TQ+, torque capscrews to
values shown in Table 2 using crisscross pattern in 20%
increments until the full torque is achieved on all
capscrews.
Note: Torque values are based on a nut factor, K = 0.20.
12. If holder configuration is TQ or TQ+, reconfirm the gap per
step 10 after the capscrews are torqued per Table 2.
INSTALLATION
1. Place gaskets on top and bottom of assembly. Gaskets
subject to relaxation or cold flow are not recommended for
use with the holder assembly. Spiral wound gaskets are
not suitable for certain sizes and flange ratings. Reference
warning notes on page 1.
2. Carefully slide rupture disc assembly between companion
flanges.
WARNING: For installations directly under a pressure relief
valve that utilize a spool/spacer, ensure spool/spacer is
installed between the outlet of the holder and inlet of the
pressure relief valve. SRL , XL , and ATLAS-L holder
sizes 12” and smaller are not suitable for direct-coupling to a
pressure relief valve; they must utilize a high-profile holddown,
spool, or a suitable spacer. Atlas holders 14” and larger
require a spool piece if under a pressure relief valve. Refer to
Fike Technical Bulletin TB8105 for code requirements.
WARNING: Double check the orientation of the rupture disc.
Verify flow arrows on the holder and disc tag are pointed in the
same direction as process flow.
3. If necessary, clean threads on studs and nuts. Wire
brushing is usually sufficient. il studs with a light oil such
as SAE grade 20. Do not use studs and nuts that show
evidence of galling.
4. Finger-tighten flange studs and nuts.
5. Refer to Appendix A to obtain torque value. Locate
nominal disc size and flange rating. This is the
recommended torque value.
6. Using the crisscross pattern shown in Figure 8, apply
torque in 4 steps of 25% increments. For example, if the
torque required from Appendix A is 100 ft-lb, the torque
should be applied in 25 ft-lb increments. Apply 25 ft-lb to
each nut, then 50 ft-lb, then 75 ft-lb, etc. For larger
quantities of bolts than shown below, use a similar
crisscross pattern.
NOTE: Follow the torque instructions in this document
unless a specific torque requirements is stated on the
Rupture Disc and/or Rupture Disc Holder Tag.
Figure 8 - Bolt Tig tening Sequence
7. After recommended torque has been achieved, perform a
final tightening in a clockwise bolt-to-bolt fashion to ensure
that all studs have equal loading.
CHECK GAP BETWEEN BASE AND H LDD WN AFTER
EACH T RQUE STEP. MAINTAIN AN EQUAL DISTANCE
BETWEEN C MPANI N FLANGE FACES N ALL SIDES.
8. Experience has shown that, in some installation
conditions, it may be necessary to re-torque the flange
bolting after the system has operated through normal
pressure and temperature cycles. Under normal operating
conditions, the rupture disc is recommended to be
replaced yearly. Severe operating conditions may require
that the rupture disc be replaced more often.

Appendix A – Stud Torque Values
NOTE: Torque values in Appendix A are based on a nut factor K= 0.2. Adjustment to the torque should be considered if the installation
utilizes bolting/lubrication with a nut factor other than K= 0.2. The following expression may be used for correction:
Equation 1: T
2
= (T
1
/K
1
)*K
2
where T
1
and K
1
are the Fike default torque and nut factor values.
NOTE: Torque values in Tables 1 to 3 are recommended values, but may be increased up to 50% to achieve an increased gasket seal.
If the torque values are unsatisfactory, consult factory.
