Application FAQ’s / Lessons
Learned
Head Type
Rubber is an incompressible solid, it can only be deflected
•
•
Type 1, 3, 4 – Minimal Deflection;
Highest Energy Absorption;
Application: High Load/Over Slam
Type 2, 5 – Greater Deflection; Lower
Energy Absorption; Application: Low
Energy Dynamic Load
Type 6 – Most Deflection; Lowest
Energy Absorption; Application: Low
Energy Static Load; Non-linear
Compression Curve Characteristic;
Ultimate Acoustical Soft Sound and
Feel.

Ergonomics:

Retention:

•
Best: Pull thru – Must have access to
back panel
Better: Push thru – Tool necessary
Good: Twist in – Line up with tear
drop shaped hole in substrate & rotate
360
–
PULL-THRU STYLE 2
Best: Twist in – Maximum retainer ratio
& durometer available
Better: Pull thru – Solid neck &
retainer
Good: Push thru – Hole for
installation allows for deflection
Cost:

–
PUSH-IN STYLE 1
Best: Pull thru – Difference in tooling
Better: Push thru – Addition of core
pins in tool cost
Good: Twist in – Lower cavitations
TWIST-IN STYLE 3
Substrate Requirements
• Metal Substrate:
– Holes punched from installation side yield a beneficial die roll & burr
– Holes punched from opposite side yield a detrimental die roll & burr – resulting
in eventual ergonomic issues and poor bumper retention
• Plastic Substrate:
– 1/2mm radius should be molded into the hole from installation side
– By varying the local substrate thickness at the hole, a wider selection of
existing parts can be attained
• General Substrate:
– Some interference in groove height dimension is allowable to broaden the
selection of build to order parts
• Best Retention:
– Match hole diameter with groove diameter line-to-line
– Groove thickness to substrate thickness, line to line or slightly tight
Installation
•
•
•
Insertion tools for push-in bumpers should have a
diameter slightly smaller than the insertion hole.
Insertion tools usually have a shoulder, to prevent
piercing the carrot.
If installation is difficult try:
•
•
Armada Rubber proprietary molded in lubricant that can
be made in almost any durometer and in any material.
As a last resort try a small amount of Rosewater
NOTE: Many factors affect installation efforts: Operator Attitude; Hole Size;
Durometer of the bumper; Proper install tool; Operator’s angle of attack;
Shape of hole (burr or die roll); Temperature (ambient and that of the rubber
bumper, warmer is better); Humidity; Bloom or Surface Contaminants if any
Recessed Head Bumpers
• These bumpers are specifically designed to receive
a fastener.
• If bumper ships with integrated fastener interference
fit is necessary.
• For bumpers attached with screws, depending on
durometer & torque requirement, a washer may be
needed to prevent damage during installation
• Recessed head bumpers are chosen when
maximum retention is essential for the application
Hole Plugs
• On plane sealing – this style
has a mushroom shaped head
that seals on the surface –
excellent for off-plane hole
distortions
• Radial sealing in the through
hole – Diameter interference fit
of 1 to 2mm necessary

Valves
• Armada Rubber has highly engineered single shot valve systems
capability
• One or two way valves to selectively move water and/or air
• Multi-piece assembly valves protect valve function against mud,
stone impingement and other environmental issues
• Applications: Head/tail light vent tubes that inhibit water/dust
intrusion; structural foam injection valves; one-way plenum drains;
duckbill drains, etc.
Line Plugs
Line plugs require interference between parts for the
plug to retain. This interference occurs between the
inside diameter of the line and the outside diameter of
the plug.
Grommets
• Grommets act as isolators or protect a part that travels
through them.
• The dimensions of a grommet must be close to that of
the substrate into which it will be installed.
• Grommet Applications are: Isolators, drains, wire/tube
pass through.
Grommets
• Grommets are dynamic energy absorbers
• For ease of installation a lead-in is recommended
• Grommets for mounting applications such as ABS units
mounted to the bracket and vehicle are critical for noise
and vibration abatement.
Caps
• Caps can be used to either keep fluid from
flowing in or out of an area, they can be used as
a bumper or as a stand off.
• Interference between the I.D. and O.D. should
be 10 – 15%.
Specialty Parts
• Stabilizer/isolator pockets for brake/fuel line;
single piece engineered latch pocket/receiver.
• Dampeners
• Vacuum connectors
• Gap hider/cosmetic close-out generally molded
in TPO, TPE or Santoprene.
Summary
