Fittings & Couplings for
High, Medium, and Low Pressure
Chemical Hose
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 Top

Working pressure ratings are based on using smooth bore chemical
rubber hose, including plastic-lined.
(2) Working pressure ratings are based on using any smooth bore
rubber hose except chemical, steam,
and hot tar.
(3) For use without a hose attachment.
• For steam and hot tar hose refer to section
C.
• Working pressure ratings are based on using CampbellCrimpnology™
products only, and that proper crimping procedures have been followed.
• Working pressure ratings are maximum as listed or the hose
rating, whichever is lower.
• Refer to Temperature
Derating Chart for temperatures above 70°F.
