Style 501: Known as a “Flat Belt Type”, this non-metallic connector is primarily used for low
pressure vibration applications and can be attached to existing metal frames or duct work. The
PROCO Series 500, Style 501 duct connector can be manufactured in round or rectangular
shapes and can be attached to metal surfaces using clamps (round applications), or backing
bars (rectangular applications). The Style 501 can be manufactured in a variety of elastomers
and can be sent to the field spliced endless and/or prepared for cold field splice. See Table 1 for
material considerations.
Style 502: Known as a “Flat Belt Arch-Type”, this non-metallic connector is used for low pres-
sure applications where movements are required and can be attached to existing metal frames
or duct work. The PROCO Series 500, Style 502 duct connector can be manufactured in round or
rectangular shapes and can be attached to metal surfaces using clamps (round applications),
retaining rings (round applications), or backing bars (rectangular applications). The Style 502
Flat Belt Arch-Type can be manufactured in a variety of elastomers and can be sent to the field in
an endless connection only. See Table 1 for material considerations.
Style 190-K: Known as a “Navy Fan Connector”, the Style 190K is manufactured of 3/16" thick
polyester fabric reinforced neoprene MIL-R-6855, Class 2, Durometer 40. The Style 190-K Navy
Fan Connector can be manufactured in U-Type or Arch-Type forms depending upon application
requirements. U-Type connectors can be manufactured with a minimum 3" face-to-face overall
length. Arch-Type connectors can be manufactured with a minimum 6" face-to-face overall length.
PROCO can manufacture the Series 500, Style 190-K in both round and rectangular shapes. If
flange drilling is required for the Style 190-K Navy Fan Connectors, PROCO can drill per customer’s
specifications. Retaining rings and/or backing bars can be furnished (drilled or undrilled) upon
request. See Table 1 for material considerations.

2. Expansion Joint “Cover” (outside) can be Hypalon painted on special order.
3. Standard fabric reinforcement is polyester. Other high temperature materials are available upon request.
4. For vacuum applications, all fabric elements should retain sufficient setback from the duct to ensure that
belting does not protrude into the flow stream.
