Boss™ System
Boss™ Clamps
•
The bolts used in the Boss™ interlocking clamps are not standard bolts. They vary from
standard bolts in their length, diameter, overall thread length and material hardness. These
bolts can be retorqued, but it is
not
recommended that the bolts or clamps be reused, as
they are designed for a single bend only. Dixon
®
recommends using only factory supplied
replacement bolts.
•
Torque values for clamps are based on dry bolts. The use of lubricant on bolts will adversely
effect clamp performance.
Do not lubricate nuts and bolts.
•
for all bolt tightening sequences, please visit
dixonvalve.comFeatures:
•
recommended for steam service up to
450°F (232°C)
•
