CHEMJOINT™ COUPLINGS & MALE STEMS
Description
ChemJoint Couplings and Male Stems create an extremely versatile chemical hose assembly system. The system solves problematic cam & groove issues such as pressure, temperature, side load, viscosity, line dedication, and ergonomics.
Features & Benefits
• Graduated serration pattern - sharper near the interlock, rounder near the end. Grips and seals plastic lined chemical hose without cutting through the tube.
• Interlock-groove locks ferrule into place for the ultimate in holding power.
• Crimped assemblies are low profile and eliminate sharp edges from bands.
• Viton seal allows coupling to meet pressure ratings with nut hand tightened.
Recommended Hose Attachment
• Interlocking ferrules
• Preformed bands

(1) For normal fluids (not hazardous, combustible, flammable, volatile, corrosive, ammonia or LPG). Individual testing should be employed for non-normal fluids to ensure capability. Pressures shown are only valid for the fitting/coupling/attachment and hose combinations indicated and for their threaded mating parts. System working pressure does not include end pull forces. Not for plastic fittings/couplings. All hose systems must be assembled using Campbell procedures and crimp specifications. See elevated temperature derating chart above. Consult factory for reduced temperatures. Never exceed the working pressure of the lowest rated component in the hose system. Maximum working pressure includes the highest pressure the system will experience, such as spikes, surges, and water hammer effects. (For example: If a system consists of a hose rated to 150 PSI and the couplings are rated to 500 PSI, the system should never be used in excess of 150 PSI.)

(2) Hose descriptions:
Air - any smooth bore rubber air or water hose. Includes most general purpose hose
Chemical – any smooth bore rubber chemical hose, including plastic lined (PTFE, UHMW, XLPE). Does not include soft tube hose
PVC – any smooth bore PVC or vinyl hose
Rubber – any smooth bore rubber hose except steam, hot tar & asphalt, chemical, and soft tube hose
Soft – any smooth bore rubber hose with a thick, soft tube. Usually gum rubber and some food-grade hose
Steam – includes hot tar and asphalt

Refer to Temperature Derating Chart for temperatures above 70°F.
