Combination nipples are recommended for low-pressure discharge and suction service for compatible liquids. They are not for compressible products such as air or nitrogen on sizes 1 1/4" and above.
King Combination Nipples are not recommended for steam.
The working pressure may vary with the construction of the hose, the type of clamping system used and the application.
In accordance with the R.M.A. bulletin for oil suction and discharge hose, a coupled length of hose in any size, should be tested to 1 1/2 times the working pressure and held for fifteen minutes without leaking or coupling movement. For additional information and detailed instruction on testing procedures, see the Rubber Manufacturers Association (R.M.A.) handbook.
Safety Alert: Boss couplings and the steam quick disconnects are the only Dixon couplers recommended for steam service/Asset/King-Combination-Nipple-_th.jpg
The largest advantage of the notched design is that the coupling can be removed from a damaged hose by cutting away the ferrule, without necessarily damaging the fitting. After inspection of the fitting to determine its suitability for reuse, it can be reinstalled into another hose by using a new ferrule.
The notched system allows you to better manage your inventories. You can stock one stem and two ferrules, and cover the same hose range with less inventory. You must purchase a fitting and the matching ferrule to create an assembly.
For hose outside diameters of 2 4/64" and below, the couplings are crimp only.
For hose outside diameters of 2 5/64" and above, the couplings can be crimped or swaged.
Only use the NOS shank with the NOS ferrules. Due to differences in dimensions and tolerances for safety reasons, do not use other manufacturer's stems or ferrules with Dixon Holedall products.

PF shank King Combination nipples have the same shank pattern as found on the PF style cam and groove fittings sold. This shank design was developed specifically for chemical transport hoses having Crosslinked Polyethylene (XLPE) or Ultra High Molecular Weight Polyethylene (UHMW) tubes, where shank retention can be a problem when using conventional band clamps.
Recommended for discharge and suction service
Not intended for compressed air
Working pressure is given at 70ºF maximum
The working pressure may vary with the construction of the hose, the type of clamping system used and the application.

There are two grooves on the crimp style King Combination nipples. The second groove is the roll stamp groove which has the part number and call 'Dixon' stamped on it. This groove is a smooth concentric groove so that the stamp can be legible.
Only use the crimp style shanks with the crimp style sleeves and ferrules. Due to differences in dimensions and tolerances for safety reasons, do not interchange other manufacturer's products with Dixon products.
