Our leadership has been earned through consistent application of solid engineering principles stringent quality standards and product innovation to produce safe and reliable metal expansion joints and flex connectors for hvac piping and ducting applications.
Hvac ductwork expansion joints.
Products services for hvac duct expansion joints flexible expansion joints 437 companies description expansion joints connect two fixed assemblies or pipes and allow movement due to service load shock or thermal cycles.
Flexicraft fully molded reinforced rubber duct expansion joints used as fan connectors are available in round and rectangular configurations in virtually any size.
Engineered with a leed qualifying zero voc gasket this ductwork can eliminate the need for additional sealing along the longitudinal seams and transverse joint.

Hvac expansion joint product selection guide.
Use greenseam snap pipe duct and fittings from grainger to help with your commercial and residential hvac applications.
Food grade is also available.
Duct type expansion joints flexible connectors are used in duct systems to reduce vibration transmission and shock and accommodate thermal movements at minimum stress to the ductwork.
These duct expansion joints allow movements in low pressure gas services up to 250f for epdm and nitrile and also 400f for viton.
Each box of metal duct contains five 5 ft.
In seismic zones they accommodate differential motion across building expansion joints as well.
