SERIES 150: 150 PSI WORKING PRESSURE
SERIES 250: 250 PSI WORKING PRESSURE
PERFORMANCE FEATURES
• High temperature resistant fabric reinforcement for
operating temperatures up to 350°F when required
• Components are pressure cured, resulting in
structurally sound, long service life
• Optional exterior coat of Hypalon
®
paint provides
additional protection against oxidation, corona,
acid splashing or acid fumes
• Reduces water line noises and vibrations caused
by the pipe wall
• Reduces “water hammer”
• Prevents electrolytic action by eliminating
metal-to-metal contact
CONSTRUCTION FEATURES
Custom built to your exact specifications in lengths up to
12 ft and diameters from 1" to 48".
• C hoice of eight cover and tube elastomers
• Choice of cover to match tube materials or different
materials for superior resistance to external conditions
• Carcass constructed of multiple plies of polyester tire
cord to minimize elongation
• Baked Enamel, Galvanized Ductile Iron, Carbon
or Stainless Steel Split Backup Rings
• 150 lb ASA drilling is standard. Other drillings
or completely customized drillings as required.
Opposite flanges can have different drillings
to serve as transition pieces
• Helical wound spring wire runs through the carcass
for radial reinforcement
• Can be built with permanent offset to compensate
for existing or designed piping misalignment

SERIES 150
(Working Pressure 150 psi and Full Vacuum)
The Vibraflex 150 reinforced rubber pipe is hand-built by our
skilled craftsmen. To minimize pipe elongation, the carcass
is constructed of multiple plies of high tensile polyester tire
cord or Kevlar
®
for high temperatures. Helical spring steel wire
is imbedded in the carcass to prevent kinking or crushing as
well as for radial pressure reinforcement. A variety of cover and
tube elastomers are available, offering superior chemical,
aging and temperature resistance from -30° to +250°F operating
temperatures. Please refer to the choices on the table on the
next page.
SERIES 250
The Vibraflex 250 has all the features of the 150, with working
pressures up to 250 psi and full vacuum.
SERIES HT150 & HT250
The Vibraflex HT150 & HT250 are a High Temperature series.
The tube and cover are either EPDM or Viton
®
and the
reinforcement is Kevlar
®
for full pressure service up to 350°F.

1. Anchor rigid metal piping securely. Do not weld near
rubber.
2. Use suitable hangers so weight is not on the Vibraflex hose.
3. Measure lengths accurately, then install Vibraflex in exact
normal length, avoiding compression or elongation.

4. T ighten bolts in equal steps until rubber flange bulges
slightly between retaining ring and adjoining pipe flange.
Check bolt tightness several days after initial operation
and then periodically thereafter.
5. Check temperature and pressure ratings for intended
service.
