“HOOD SEAL” ADAPTOR ASSEMBLY
This adaptor is a mechanical bulkhead fitting that produces a
liquid-tight seal around 1/2 in. EMT conduit when installing the
detection line through restaurant hoods and duct. The adap-
tor accepts a high temperature pulley elbow and, when used,
correctly positions the elbow or conduit in line with the conduit
adaptor hole in the detector bracket. The “Hood Seal” elimi-
nates the need for multiple elbows when penetrating the top of
a hood when installing the detection line. “Hood Seal” Adaptors
are available in quantities of six as Shipping Assembly Part No.

containing both. Listed below are the various shipping assem-
bly part numbers.
