With the Scotchlok™ series of tools and connectors,
service providers can meet the demand for enhanced
customer services such as high-speed internet, video-on-
demand, and video conferencing. Scotchlok connectors
also oer full wire-range capability, increased port size to
accommodate up to 2.08 mm (0.082 in) insulation sizes,
and solvent-resistant plastic construction.
As new technologies migrate into the local loop, the
importance of reliable connections in the embedded
plant has increased exponentially. Each connection is a
potential point of failure in high-bandwidth applications,
which could require additional time and expense for a
technician to repair. That is where the full line of Scotchlok
connectors can really make a dierence.

Scotchlok™ Butt Connectors
Scotchlok Butt Connector UR
The Scotchlok UR connector accepts two or three solid copper conductors for butt splicing.
The connector is lled with a sealant to provide moisture resistance.
Scotchlok Butt Connector UY
The small size of the Scotchlok UY connector reduces the splicing bundle outside diameter
(OD) to a minimum. The connector’s two ports accept two solid copper conductors. The
connector is lled with a sealant to provide moisture resistance.
Scotchlok Butt Connector UR2/UR2-D
The Scotchlok UR2/UR2-D solvent-resistant connectors accept two or three solid copper
conductors that can be of dierent wire gauges, for butt splicing. The UR2 connectors are lled
with a sealant to provide moisture resistance. The Scotchlok UR2-D connector is a dry version.
Scotchlok Butt Connector UY2/UY2-D
The small size of the Scotchlok UY2/UY2-D solvent-resistant connectors reduces the splicing
bundle OD to a minimum. Two ports accept two solid copper conductors that can be of
dierent wire gauges. The connector is lled with a sealant to provide moisture resistance.
In addition, the Scotchlok UY2 connector is available in a dry version, Scotchlok UY2-D
connector.
Scotchlok Butt Connector UAL
The Scotchlok UAL connector is a sealed, moisture-resistant, two- or three-wire connector.
Outside ports accept solid copper, aluminum, or a combination of both.
Scotchlok™ butt connectors employ a specially designed wire-insulation displacement contact to make a reliable
electrical connection to each wire. A “live-spring” joint is made by driving the wire down into the “U” contact connector.
This simple process displaces the insulation and grasps all conductors with a rm, resilient pressure in an all-in-one motion.
No stripping of wire insulation is required. Scotchlok butt connectors include a factory-installed sealant to protect against
corrosion and seal out moisture. They are also available in a dry/ame-retardant version for central oces and vaults.
A variety of sizes and wire combinations are available to accommodate almost any need.
Corning Optical Communications Scotchlok Brochure | CRR-955-AEN | Page 5
Scotchlok Butt Connector UP2
The Scotchlok UP2 connector is a dry, ame-retardant, two-wire UL-Listed connector for use on
paper, pulp, or PIC cable where moisture resistance is not needed. (UL-recognized component).
Scotchlok Clearing Cap UCC
Each moisture-resistant Scotchlok UCC clearing cap isolates a full cable pair. The conductors
are held rigidly in place with a plastic blade. The Scotchlok UCC accepts two wire combinations.
Scotchlok Butt Connector UP3
The Scotchlok UP3 connector is a dry, ame-retardant, two- or three-wire connector for paper,
pulp, or PIC cable where moisture resistance is not needed. (UL recognized component).
Scotchlok Self-Stripping Drop-Wire Connector 557TG2
Use the Scotchlok 557TG2 aerial drop-wire connector to electrically connect two solid copper
conductors, insulate the connection, and provide moisture protection.
Corning Optical Communications Scotchlok Brochure | CRR-955-AEN | Page 6
Scotchlok™ Tap Connectors
Scotchlok Tap Connector UB2A/UB2A-D
The Scotchlok UB2A/UB2A-D connectors have a precrimp feature that gives the craftsperson
a time-saving edge. By positioning the connector on the conductor and precrimping, the
conductor is prevented from slipping out of the connector before the crimp is completed. A
factory sealant protects against corrosion and seals out moisture. In ready-access closures,
these connectors help eliminate cutting cable pairs, opening circuits, and piecing out wires.
The Scotchlok UB2A-D connector is a dry version of the Scotchlok UB2A connector.
Scotchlok Inline Connector U1B
The Scotchlok U1B connector is a sealed, moisture-resistant, four-wire (one full-pair) inline
connector for larger-gauge solid copper. (AWG 19-16 solid copper conductors).
Scotchlok Inline Connector U1R
The Scotchlok U1R connector is a sealed, moisture-resistant, four-wire (one full-pair) inline
connector for larger-gauge solid copper. (AWG 24-19 solid copper conductors).
Scotchlok™ tap connectors are real time savers. They allow the user to tap into another wire without interrupting service.
A U-shaped element inside each connector displaces insulation material and makes contact with the copper conductor.
Scotchlok tap connectors also include factory-installed sealant to protect against corrosion and seal out moisture.
They are also available in a dry version for central oces and vaults.
Scotchlok tap connectors are fast to install, easy to use, and available in a wide range of common wire gauges.
Tap connectors allow direct tapping into existing solid copper conductors without interrupting service. The precrimp
feature helps to hold the wires in place until the connector is crimped and the splice is complete.
Scotchlok Inline Connectors
Scotchlok inline connectors are a safe and simple way to make a secure connection. These full-pair,
sealed, moisture-resistant connectors are designed to accommodate a wide variety of wire ranges.

Scotchlok Cartridge Tool E-9C with Case and Gauge
With an automatic cartridge feed, a 7-to-1 mechanical advantage, and ratchet
action, the Scotchlok E-9C tool allows the craft person to complete a crimp
with one hand, freeing the other hand for wire handling. The tool is designed
for cartridges with Scotchlok butt connectors.
Scotchlok Crimping Tool E-9BM
This heavy-duty tool is capable of crimping all Scotchlok connectors. Its
parallel closing action and adjustable jaws provide a 10-to-1 mechanical
advantage, allowing it to handle all wire gauges.
Scotchlok Crimping Tool E-9E
A completely parallel closing action and a 4-to-1 mechanical advantage make
the lightweight Scotchlok E-9E crimping tool a versatile addition to any craft
person’s toolkit. With these features, the Scotchlok E-9E tool will crimp all
Scotchlok butt-and-tap connectors in all wire gauges.
Scotchlok Crimping Tool E-9Y
The Scotchlok E-9Y tool has stepped jaws, a long nose, and a side wire cutter
to crimp two- or three-conductor splicing. The Scotchlok E-9Y tool is not
recommended for 19-gauge (0.9 mm) and larger conductors.
Scotchlok Crimping Tool E-9J
The Scotchlok E-9J tool is a lightweight, handheld tool featuring a
single-stroke, parallel crimping action with a work-saving 10-to-1
mechanical advantage over applied hand force. For use with Scotchlok
butt-and-tap connectors.
Scotchlok™ Tools
To complement our line of ecient, reliable Scotchlok™ connectors, Scotchlok crimping tools are built to do the job right,
and do it fast. All Scotchlok tools are engineered to t comfortably in hand while providing mechanical advantages
for less operator fatigue. From automatic cartridges to adjustable jaws, there’s a tool designed to meet your specic
application needs.
