- 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. Consult JGB for recommendations.
- 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 1½ 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.
