4.2 Applications

The sealing sleeves covered by this document are designed for immersion resistant splice

sealing when no more than one wire is inserted through each hole of the seals. In some

instances a maximum of two wires of specified sizes can be inserted through each hole of

the seals, with factory evaluation and approval.

5. Procedure:

These procedures are for installing crimp splices and sealing sleeves of the D-436-XX

and D-200-XX series. Separate procedures are provided for parts conforming to

paragraphs 4.1.1, 4.1.2, and 4.1.3.

WARNING

Follow installation instructions carefully. Use adequate ventilation and

avoid charring or burning during installation. Charring or burning the

product will produce fumes that may cause eye, skin, nose and throat

irritation. Consult Material Safety Data Sheets RAY5106 for further

information.

5.1 Part Selection

Select the proper splice components for the application according to the applicable

drawing or to the Selection Guide, or Customer Drawings (CD). See section 2.

5.2 Wire Preparation

(1) Strip the wires to be spliced. If any conductor is to be folded back to increase the

effective cross-sectional area, strip that wire to twice the specified strip length.

Strip lengths:

The strip length for a particular crimp splice equals the length of the crimp barrel plus

0.8 - 1.6 mm (1/32 –1/16 inch) See figure on next page.

For most AWG 12 and smaller crimp splices, the correct strip length is

7.9 - 8.7 mm (5/16 - 11/32 inch).

(2) If directed in the splicing tables to fold any conductors back, fold the appropriate

conductor(s) as shown below.

5.3 One-to-one In-line Splices and Two-wire Stub Splices

5.3.1 Select proper slice components and prepare the wires as shown. (See 5.0.1, 5.0.2)

5.3.2. Splicing Procedure

(1) If making an in-line splice, slide the sealing sleeve onto either wire.

For stub splices, the sealing sleeve will be installed later.

(2) Crimp the wires in the crimp splice as shown in the appropriate figure below.

The gap between the end of the wire insulation and the crimp splice must be

0.8 - 1.6 mm (1/32 - 1/16 inch).

(3) Center the sealing sleeve over the splice area as shown.

Unless otherwise specified dimensions are in millimeters. [Inches dimensions are in between brackets]

(4) Heat (see Warning note) the sealing sleeve to shrink it and melt the seals as follows:

a. Use one of the heating tools listed in section 3.

b. Heat from one end toward the other. For stub splices, start at the end from

which the wires exit.

c. Continue heating until the seals melt and flow along the wire insulation and if a

stub splice, one seal melts and closes the end.

d. Allow the assembly to cool undisturbed.

WARNING

The heating tool and the assembly become hot during the installation of

the Sealing Sleeve. To prevent burns, allow tool and the assembly to cool

down before handling.

(5) Inspect the completed sealed splice per section 6.

5.4 Multiple-to-one In-line Splices and Multiple-wire Stub Splices

5.4.2. Splicing Procedure

(1) Insert one of the multiple wires through each hole of the multiple-hole seal, and slide

the sealing sleeve back over the multiple wires as shown.

(2) Crimp the wires in the crimp splice as shown in the appropriate figure below.

* Make sure that the multiple wires do not become crossed between the multiple-hole

seal and the crimp splice.

(3) Center the sealing sleeve over the splice area as shown.

(4) Heat (see Warning note) the sealing sleeve to shrink it and melt the seals as follows:

a. Use one of the heating tools listed in section 3.

b. Heat the multiple-wire end first, until the multiple-wire seal melts and flows around

and along the wire insulation.

c. Move the heat toward the single-wire or open end, shrinking the sleeve along the

way.

d. Heat the second end until the seal melts and flows along the wire insulation or

closes the open end.

e. Allow the assembly to cool undisturbed.

WARNING

The heating tool and the assembly become hot during the installation of

the Sealing Sleeve. To prevent burns, allow tool and the assembly to cool

down before handling.

(5) Inspect the completed sealed splice per section 6.

5.5 Multiple-to-multiple In-line Splices

5.5.1. Select proper slice components and prepare the wires as shown. (See 5.0.1, 5.0.2)

5.5.2. Splicing Procedure

(1) Insert the multiple wires coming from one direction through the integral seal and

sleeve, one wire per hole, as shown.

(2) Insert the multiple wires coming from the other direction through the separate seal,

one wire per hole, as shown.

(3) Crimp the wires in the crimp splice as shown below.

Make sure that the multiple wires do not become crossed between either one of

the multiple-hole seals and the crimp splice.

(4) Push the separate multiple-hole seal up against the crimp splice.

(5) Position the sealing sleeve over the splice and over the separate multiple-hole seal so

that the separate seal is fully seated within the end of the sealing sleeve as shown.

Squeeze the wires together to hold the separate seal against the splice while

moving the sealing sleeve into position.

(6) Heat (see Warning note) the sealing sleeve to shrink it and melt the seals as follows:

a. Use one of the heating tools listed in section 3.

b. Heat the end with the separate seal first, until the seal melts and flows

around and along the wire insulation.

c. Move the heat toward the end with the integral seal, shrinking the sleeve

along the way.

d. Heat the end with the integral seal until the seal melts and flows around

and along the wire insulation.

e. Allow the assembly to cool undisturbed.

WARNING

The heating tool and the assembly become hot during the installation of

the Sealing Sleeve. To prevent burns, allow tool and the assembly to cool

down before handling.

(7) Inspect the completed sealed splice per section 6.

6. Inspection:

6.1 Inspection for Proper Assembly

(1) The sealing sleeve must be centered over the splice area so that the melted seal

overlaps the wire insulation by at least 1-1/2 times the diameter of the wire insulation.

(2) The wire insulation must end at a point 0.8 - 1.6 mm (1/32 –1/16 inch) from the

crimp splice.

6.2 Inspection for Proper Heating

(1) The sealing sleeve must be completely shrunk onto the splice area and wire insulation.

(2) The seals must be melted and flowed so as to lose their original shape as described

below:

a. If sealing a single wire, seal must be flowed along the wire insulation.

b. If sealing multiple wires, melted sealing material must be visible between

the wires where they exit from the sealing sleeve.

* Look between the wires to make sure that the center portion of the seal

has melted.

c. The free end of a stub splice must be completely sealed.

inspection of the splice (overheated condition).

6.3 Inspection for Damage

(1) The sealing sleeve must not be cut or split.

(2) The wire insulation must not show signs of mechanical damage or overheating, such

as cuts, tears, melting, charring.

7.1 Insufficient Heat (Unacceptable)

Meltable Inserts have not flowed

Then sealing sleeve not fully recovered

7.2 Proper Heating (Acceptable)

Meltable Inserts have flowed so as to lose their original shape

Then sealing sleeve is fully recovered
