Resistoflex PTFE Expansion joint:

PTFE Expansion Joints are used to compensate for movement, misalignment and/or vibration in piping systems. Generally, the more convolutions in the joint design, the greater the range of motions it can compensate. Expansion joints should never be used to compensate for rotation about the pipe axis.

Resistoflex uses only TEFLON® T-62 resins by DuPont because of the extraordinary performance it provides

 R-Series:

Steel bolts limit axial extension, offset, and angular misalignment. They also restrict harmful torsional movement.

Limit-rods are pre-set at the factory with elastic stop nuts (this setting must not be modified).

Reinforcing rings provide pressure-retaining capability.

E-Series:

Stainless steel aircraft-grade cables limit extension.

Cable-limited joints allow for greater offset and angular misalignment than bolt-limited joints.

Neutral lengths are common to other manufacturers, allowing drop-in replacement of underperforming joints in many cases.

Reinforcing rings provide pressure-retaining capability.

Resistoflex PTFE Special Shape:

Available lined with TEFZEL®.

TEFZEL® has better chemical resistance to 300 deg F than any plastic except TEFLON ®.

Large diameter capability up to 24" NPS.

Liner is seamless with uniform thickness.

Liner is mechanically bonded to metal substrate.

Standard liner thickness is .200" nominal, with thicker liner available.

Resistoflex can line customer-supplied housings.
