Styles 214 and 215

nnnn

These PTFE concentric spool-type flexible couplings are

nnnn

designed to reduce noise and compensate for expansion,

nnnn

contraction and minor piping misalignment in chemical

nnnn

processing, air conditioning and heating systems.

nnnn

Benefits

nnnn

■ Convolution shape provides extra-long flex life at high

nnnn

temperatures

nnnn

■ Proprietary contour molding process ensures consis-

nnnn

tent wall thickness for blowout resistance

nnnn

■ PTFE body withstands corrosion, water, steam, and

nnnn

most chemicals and gases

nnnn

■ Preset restriction bolts prevent over-extension

nnnn

■ Available silicone-free

nnnn

Design

nnnn

■ Complete assembly includes fluorocarbon resin

nnnn

PTFE body, plated ductile iron flanges, polyethylene-

nnnn

covered restriction bolts and corrosion-resistant rein-

nnnn

forcing rings

nnnn

■ Standard sizes from 1" (25 mm) through 8" (200 mm)

nnnn

pipe I.D.

nnnn

Pressure and Vacuum Rating

nnnn

Garlock PTFE expansion joints and couplings have pres-

nnnn

sure ratings high enough to handle most applications. As

nnnn

the pipe size gets larger, Garlock increases the bellows

nnnn

thickness and the strength of the reinforcing rings to com-

nnnn

pensate for the change in internal forces. This permits the

nnnn

same high pressure rating for all sizes.
