Cam & Groove Couplings for Liquid, Bulk, and Chemical Transfer

"Campbell Cobra" vs. "Standard Cobra"

“COBRA” is the trade name for our entire line of cam & groove couplings. “Campbell COBRA” is the upgraded versions of Parts C and E. Although imported, Campbell COBRA C’s and E’s are designed by Campbell and produced to strict Campbell specifications.
Features & Benefits
• Designed for use with Campbell Interlocking Ferrules.
• 360° interlock groove on fitting locks ferrule into place for the ultimate in holding power.
• Shank and ferrule lengths are matched for performance and to avoid potential hose tube or hose cover damage (right).
• Serrations designed to grip, seal, and protect hose when crimped. Note: Traditional “two bump” designs are for banding, not crimping. Campbell does not recommend crimping on “two bump” shanks.
• Crimped assemblies are low profile and eliminate sharp edges from clamp buckles.
• Couplings use the same ferrules as Crimpnology Nipples, ChemJoint Couplings, and Goodyear InstaLock Cam & Groove Couplings to keep your inventory as flexible as possible.
• Designed to couple and interchange with couplings made to ASTM F1122, CID A-A-59326, MIL-C-27487.
Recommended Hose Attachment
• Interlocking ferrules
Recommended Use
• Multi-purpose liquid, chemical, bulk handling
Special Feature: Locking Handles
• Locking handles (right) can be purchased assembled onto the coupling or as a kit and retrofitted onto existing inventory ... another easy and cost-effective way to keep inventory flexible.

(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

(5) Campbell COBRA Cam & Groove Couplings are identified by the name “Campbell” on the body, by the ferrule interlock groove, and by the part number, which includes a “C” suffix. Not for air or gas service.

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