The model listed above has electrodes fitted with iridium discs held in place by a double retention system.
The design also utilizes a monolythic resistor set-up.

BG SPARK PLUGS

Models RB105-1 And RB114-1

Have Long Insulators For
Extra Flashover Protection

• 2" insulator provides extra flashover protection.

• Iridium electrodes resist erosion at high temperatures.
• High temperature non-conductive glaze on insulator
resists flashover.
• Extra thick cycle weld crimp over nickel gasket seals
for zero gas leakage and assured insulator retention.
• Conductive glass seal assures zero gas leakage.
• Folded steel gasket prevents plug loosening during
operation.

A unique cooling process

is why BG plugs
last longer. . .

The foremost way that spark plug manufacturers change

heat range of a spark plug is to change the length of the
ceramic nose — the length measured from the sealing
gasket downward to the firing end. A shorter ceramic
nose makes the spark plug “colder,” but also makes it
more prone to fouling because the electrical path is
shortened. Only BG uses cast silver in direct contact
with the ceramic insulator to facilitate cooling — this
allows BG to offer “colder” spark plugs with adequate
nose lengths to prevent fouling.

Installation Tips

• For best results, install Spark Plugs to the engine

manufacturer’s recommended torque. Typical
torque values are:

Thread Size Torque*

7/8" -18 70-80 ft. lbs.
18mm 38 ft. lbs.
14mm 25 ft. lbs.

*Reduce torque values by 20%

when using anti-seize compound.
• Use BG Mica Lubricant (BG Part No. A718) on the
plug threads to prevent thread seizure.
• Use BG Hole Conditioning Tool Part No. 21045 to
clean cylinder threads and gasket seat in one

• Avoid touching plug insulator during installation.
Hold plug by metal shell part only.
• Use a good quality spark plug boot to maximize
plug life.

BG’s COIL TESTER MAKES
TROUBLESHOOTING EASIER. . .

BG’s CT300 Coil Tester is a portable instrument

designed to check the condition of the primary and
secondary windings of a capacitor discharge coil. The
unit is powered by four “C” size dry cell alkaline batteries.
The primary voltage is adjustable from 0 to 300 volts DC.
The spark gap tests the secondary output of a coil at 28
to 30 KV. The basic system includes a set of ignition
leads to test unshielded capacitor discharge coils.
Optional leads are available to test shielded coils. Com-
plete instructions, including voltage settings for various
manufacturers’ coils, are provided.

• PORTABLE – Allows on-site troubleshooting.

• COST EFFECTIVE – Pays for itself in “saved” coils
and reduced downtime.
• EASY TO USE – Complete instructions provided.
• INCLUDES CABLES*, CARRYING CASE, AND
BATTERIES – Optional leads available for
shielded coils.

PT500 PRIMARY TESTER

BG’s PT500 primary tester is a portable instrument

designed to check for defective and worn wiring by
detecting current leaks to ground. The unit is powered
by 4 “C” size dry cell batteries. Output voltage is
adjustable from 0-500 volts DC. A voltage drop from
the initial setting indicates leakage.

• Checks primary wiring and connectors.

• Performs same function as a meggar but is easier to
operate.
• Shows shorts to ground that will not appear with an
ohmmeter.
• Includes batteries, probe lead, carrying case, and
complete instructions.

Stop costly ignition problems before they begin: check

your primary wiring & connectors with BG’s PT500 primary
tester.

 “SEAL-ON” SPARK PLUG BOOTS

BG’s “Seal-On” Boots prolong spark

plug life because they seal out dirt
and moisture. . .

Engine laboratory tests have shown that when the SEAL-ON Boot is
used, flashover voltage is increased by 8-10KV. Unlike conventional
spark plug boots, the BG “SEAL-ON" Boot is machined from teflon to
specific spark plug dimensions and seals tightly on the spark plug
insulator. The boot design incorporates an industry standard type
bayonet connector for ease of installation. The kit includes a teflon
grommet that is press fit into the upper end of the assembly so that
the boot is sealed top and bottom – at the secondary lead and at the
plug insulator. Kits are also available for use with “hi-resistance” wire,
which includes the stud and stud support required to terminate this
type of wire (Assembly layout shown on page 49). Optional SEAL-ON
Boot kits are also available for applications where 5/16" ID
silicone hose is used. Available with DSTM connector.**

Extend Spark Plug Life
In Demanding Applications
Engine laboratory tests have shown that when a tight
fitting spark plug boot is used, spark plug life is
increased. Now BG introduces a composite ceramic –
teflon extension that incorporates a teflon coated
VitonTM “O” Ring for increased sealing pressure.
Because the voltage necessary to “flash-over” the plug
insulator is increased, spark plugs will operate at larger
gaps that previously resulted in plug failure. . .
• High alumina ceramic prevents dielectric breakdown
due to corona cutting.
• VitonTM “O” Ring increases sealing pressure, yet
makes extension easier to install.
• Patented DSTM Connector uses a double spring and
will not loosen like rajah types.
• Model available for use with silicone hose
(stud connection).

SPARK PLUG LEADS

COIL CONNECTOR TYPE 3

New CetraTM Spark Plug Leads have a non-metallic internal shield that
permits use of timing lights, oscilloscopes, and other monitoring devices. . .

FEATURES
• Monitoring engine performance is faster and easier, resulting in reduced downtime and improved
operating efficiency.
• SAFER-Multi-Fault Protection: Two independent insulation layers must be breached for a spark to occur.
An internal conductive shield provides a safety path to ground.
• May be used with BG All Weather Extensions (see pages 26 & 27).
• May be used with unshielded spark plugs when used with BG’s CETRATM Series Extensions (see page 32).

PLUGS WITH BG’S NEW CETRA LEADS. . .

And BG’s Unique CetraTM extensions extend plug

life too!

• Teflon coated Viton “O” Ring seals tightly on the spark plug insulator.
Because the voltage necessary to “flashover” the spark plug insulator
is increased, spark plugs will operate at larger gaps that previously
resulted in plug failure.
• Greatly reduces spark plug cost by permitting the use of top threaded
spark plugs instead of shielded spark plugs.
• High alumina ceramic insulator prevents dielectric breakdown.
• May be used with CetraTM leads or conventional shielded leads.

BG Electric Feedthroughs provide a leakproof electrical connection through the walls of a variety of pressure vessels.
BG Electric Feedthroughs are compatible with currently used refrigerants and phenolic oils.
BG Electric Feedthroughs have a superior leakage resistance, tested with a helium leak tester, and a standard acceptance leak rate of <1x10-6
cc/sec (He).
BG Electric Feedthroughs typical operating pressures for are from ambient to 500 PSIG.
BG Electric Feedthroughs have a greater temperature capability than similar products... up to 250 deg. F in operation service.
BG Electric Feedthroughs are built with copper conductors and brass nuts for maximum electrical current carrying ability and lowest connection
losses.
BG Electric Feedthroughs are available in a variety of sizes for most applications.
