15 Ton Ram IX 8/06

Holding the hose and ferrule firmly against the

stem shoulder and, maintaining the proper

“pocket”, engage the Ram by stepping on the foot

pedal. The internal expansion operation is

complete when the hose and stem assembly is

pushed completely over the internal expansion

plug. Release the foot pedal. Visually inspect the

coupling.

Note: If the gauge reads 10,000 PSI before internal

expansion is complete, stop. Contact Dixon for

further assistance. During internal expansion

never stand directly in front of the Ram.

Note: For internal expansion of Holedall Carbon Steel and Stainless Steel couplings, please refer to the

Internal Expansion instructions for the 15-Ton Ram using Carbon Steel and Stainless Steel Couplings.

Important! It is a prudent practice to test every length of hose after assembly and Dixon Valve & Coupling

Company recommends this as a standard practice as recommended by the Rubber Manufacturers Association.

Ensuring that the end of the ferrule is aligned with the

mark from Step 6, slide the hose with ferrule over the

shank until the ferrule contacts the shoulder of the stem.

Check to see if the proper pocket is maintained.

IMPORTANT! If there is incorrect “pocket” for the

rubber to displace into, damage may occur to the stem,

ferrule or both, which could result in coupling failure.
