HOLEDALL EXTERNAL SWAGE COUPLING SYSTEM


The Holedall coupling system provides outstanding strength, durability, safety and versatility.

The Holedall system is a method of attaching couplings to hose utilizing a draw type progressive swage. The patented Holedall couplings include a Holedall stem and a specially engineered ferrule. The hydraulic swaging of the coupling to the hose is accomplished by pushing the ferrule through a die which reduces the ferrule O. D. The ferrule penetrates the hose wall, providing a 360º uninterrupted compression band around the hose.
 
A special hydraulic ram called a Mulcoram is the only piece of machinery necessary to accomplish the coupling. Available in three different sizes - 25, 50 and 100 ton - these rams will accommodate dies and pushers of various sizes so that hoses up to 10" in diameter may be coupled.
 
This multi-purpose, high pressure coupling system requires no bolts and results in a clean coupling with no protrusions. The swaging operation is fast and hose of various lengths and different styles can be coupled. Ease of operation, flexibility and economy make the Holedall method an unequalled assembly system.
 
For almost half a century, Holedall couplings have provided long-lasting efficiency and safety unmatched by any other industrial hose fitting.
 
Couplings are available in stainless steel and carbon steel.
Couplings are furnished with pipe thread, plain end for welding, grooved or flanged ends.
 
The Holedall coupling - the most adaptable coupling available.

Holedall External Swage
Cut-Away Drawing

Streamlined, lightweight coupling consisting of ferrule and stem. There are no protrusions to snag on equipment.

Holedall stems and ferrules are specifically designed to be used together as a coupling system. Due to differences in dimensions and tolerances for safety reasons, do not use other manufacturer's stems or ferrules with Holedall products!



External Swage Stems

Designed for hose I. D.'s from 1-¼" to 10". The ferrule size depends on the hose O. D. Consult the table further down on this page for the selection of the correct ferrule. Stems are supplied in plated carbon steel and 316 stainless steel.
For higher working pressure applications, use Long style Stems & Ferrules.

External Swage Ferrules

The selection of ferrules is very important to achieve the proper coupling-to-hose assembly.
  • Ferrules are plated carbon steel.
  • Style F ferrules are used with all standard length male stems.
  • Style FL ferrules are extra long and are used with all long style stems.
  • *F64-Z requires special stem: TM64-42.
  • **FL64-Z requires special stem: TML64-42.

External Swage Notched Stems & Ferrules

  • 316 stainless steel stem with wrench flat.
  • 304 stainless steel ferrule.
  • Can be swaged on or crimped on;
    Consult the Tampa Rubber Customer Service Department for specifications on swaging and crimping procedures.
    For hose outside diameters of 2-4/64" and below, these couplings are crimp only.
    For hose outside diameters of 2-5/64" and above, these couplings can be crimped or swaged.
  • This stem can be removed from a damaged hose by cutting away the ferrule, without necessarily damaging the fitting.
    After inspection to determine its suitability for reuse, it can be reinstalled into another hose by using a new ferrule.
  • You can now stock one nipple and two ferrules, and thereby cover the same hose range with less inventory.
    You must purchase a fitting and the matching ferrule to create an assembly.
  • Cam and Groove style notched fittings are also available.
  • Turned back style notched fittings (for floating flanges) are also available.

External Swage High Pressure Couplings

These couplings are for services requiring a fitting which will withstand extremely high pressure (up to 3,000 PSI) and severe operating conditions, such as on small and medium size drilling rigs, used for slim hole, core drill, workover, seismograph, water well, blast or shot holes, etc. These extra long, rugged fittings are machined from seamless pipe and tubing with specially designed serrations. The mating ferrules are machined from heavy wall material incorporating matching serrations and rows of set screws for better coupling retention. These couplings are shipped with matching ferrules. Please provide the hose O.D. when ordering for properly sized ferrule. Make sure both ends of the hose are measured for O.D. Must be swaged with the 50 Ton or 100 Ton Ram.
