*crimp·nol’o·gy n.

systematic treatment of the art of hose/fitting attachment
a: the practical application of hose attachment methods
crimped hose assemblies
b: a capability given by the practical application of crimping knowledge
repeatable hose assemblies
c: a method, process, etc. for handling a specific hose problem
significant improvement in safety and operation





"Crimpnology" refers to Campbell Fittings' proprietary hose crimping technology...

Crimpnology enables a Campbell Authorized Distributor to build an integrated LEAK-FREE hose system using any brand or type of hose.

Crimping Features and Benefits

  • All Campbell fittings, couplings, ferrules, and sleeves are designed to work as integrated parts to meet our published performance criteria.
  • The turn-in end of the ferrule locks into the interlock groove on all fittings and couplings to ensure a 360° ferrule-to-fitting interlock.
  • The coupling/fitting serrations are specially designed for the ultimate in hose retention and sealing without causing potential tube failure.
  • The coupling/fitting shank length and ferrule length are matched to also maximize retention and sealing without hose cover damage.

Campbell's Crimpnology

WARNING: Not all hose fitting products are designed for crimping! To be safe, always ask for Campbell Crimpnology fittings and ferrules.

Crimpnology Training & Procedures ...

Campbell provides detailed assembly procedures, and in-depth, on-site crimp training for all Campbell Authorized Distributors. Contact Campbell Fittings to schedule training.

Pressure Ratings & Hydrostatic Testing

All pressure ratings (published in our catalog and website) are established and verified by extensive hydrostatic testing to a 4X working pressure safety factor*. View our Test Reports.

For example: Campbell Crimpnology Nipples are rated to 500 psi working pressure, based on tests in excess of 2000 psi.

TEST: Crimpnology Nipples crimped on 400 psi WP frac hose.
RESULT: Hose burst at 1751 psi, above the 4X safety factor.*

*The Rubber Manufacturers Association (RMA) requires that hose working pressures include a safety factor commensurate with their intended use. Hoses for oilfield use, including frac hose, are required to achieve a 4X working pressure safety factor. Maximum working pressure includes the highest pressure the hose will experience, such as spikes, surges, and water hammer effects. Never exceed the working pressure of the lowest rated component in the system.
