VITON SEAL GROUND JOINT COUPLINGS,
AIR HAMMER COUPLINGS, and MALE STEMS Features & Benefits • Viton Seal Couplings pass 1000 hour MIL-H-29210.
• Eliminates leaks with nut hand tightened.
• Viton seal (formulated by DuPont for high pressure steam
and air applications) is protected inside machined stem groove and
by swivel nut, extending working life.
• Spud does not contain plastic seat, extending working life.
• Interchangeable with old style domestic ground joint couplings.
• Machined hose ends with smooth end-detail to reduce potential
failure due to abrasion - grips, seals and protects hose.
• Interlock-groove locks ferrule into place
for superior holding power.
• Crimped assemblies are low profile and eliminate sharp edges
from bolts.
• Machined from carbon steel, cast ductile iron (meets ASTM
A395/A536 specifications) and 316 stainless steel. Recommended Hose Attachment
• Interlocking ferrules
• Interlocking U-bolt clamps Top

INTERLOCKING U-BOLT CLAMPS Features & Benefits • 360° design wraps completely around
hose for superior retention.
• Clamps fit hoses tightly without cracking, eliminating costly
rework.
• Bolts on “up side” allow easier tightening/ re-tightening
and improve “dragability”.
• Field repairable. Top

Working pressure ratings for U-bolt clamps are based on using any
smooth bore rubber hose including steam and hot tar, but excluding
chemical.
(2) Working pressure ratings for interlocking ferrules are based
on using any smooth bore rubber hose except chemical, steam, and
hot tar.
• For plastic chemical hose, refer to section
D.
• 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.
