A fire suppression fitting for mounting a conduit extending through an opening in a supporting surface. The fitting includes a main body with threaded ends and a longitudinally disposed bore. The conduit is slideably received through the bore. The fitting further includes a gasket, a lock washer and an anchoring nut. The anchoring nut secures the main body on the supporting surface and the gasket in sealing engagement around the supporting surface opening. The coupling further includes a compression nut and a compression gasket, the compression nut selectively urges the compression gasket into sealing fire impeding relation around the conduit.

1. A fitting for supporting a conduit for fire suppressant material on a supporting surface as part of a fire suppressant system, the fitting comprising an opening in the supporting surface adapted to house the conduit, and means for mounting support of the conduit at said opening including, an elongated unitary body extending partially in the opening and surrounding the conduit, a first generally annular gasket supported on said body and engaging the supporting surface about said opening, an annular surface on said body engaging said first gasket, first clamping means engaged with said body for selectively clamping said first gasket between said annular surface and said supporting surface and in sealing engagement with said surface around said opening and releasing said first gasket from said sealing engagement and means for locking said first clamping means in said engagement with said body, a compression seal surrounding the conduit and engaged by said body, and second clamping means engaged with and movable relative to said body and said compression seal for selectively urging said compression seal into sealing engagement around said conduit and for releasing said compression seal from sealing engagement around the conduit. 2. A fire suppression system comprising, a supporting surface having first and second opposite sides and having a hole therein, fire suppression means disposed on said first side of said supporting surface, a fire retardant conduit extending through said hole in said supporting surface, and fitting means for supporting said conduit and for sealing said conduit and said support surface, said fitting means including a generally cylindrical body having threaded first and second ends, said second end of said body extending through said hole and having therein a longitudinally disposed bore, said bore adapted to receive said conduit, said fitting means also including a nut integrally formed with said body and disposed intermediate said first and second ends, a generally annular gasket of resilient, temperature resistant material, said gasket received on said second end disposed between said nut and said first side of said supporting surface, a lock washer received about said second end and positioned against said second opposite side of said supporting surface, an anchoring nut threaded on said second end of said body and securing said body to said supporting surface, a compression nut threaded on said first end of said body, and a compression seal releasably engaged with said compression nut. 3. The apparatus of claim 2 wherein said bore has a substantially uniform diametral dimension, and wherein a seat is formed in said first end, and wherein said compression nut is operable to urge said compression seal into engagement with said seat thereby moving said compression seal into sealing engagement with said conduit. 4. The apparatus of claim 3 wherein said first and second ends of said main body have predetermined outside diameter, and said outside diameter of said first end is less than said outside diameter of said second end. 5. A fire suppression fitting for sealingly mounting a conduit for penetration of a supporting surface comprising: a generally cylindrical main body having threaded first and second ends, said first end defining a seat, said first and second ends having predetermined outside diameters with the outside diameter of said second end being greater than the outside diameter dimension of said first end, said second end extending through the supporting surface, a longitudinally disposed bore having a predetermined diameter adapted to slideably receive the conduit; a generally annular member integrally formed with said main body and disposed substantially centrally and extending radially from said main body, said annular member having oppositely facing forward and rearward surfaces; a gasket of a resilient, heat resistant material, said gasket slideably received about said second end of said main body and positioned in engagement against said rearwardly facing surface of said annular member, and said heat resistant gasket engaged with one side of the supporting surface; a lock washer slideably received about said second end of said main body and engaged with the opposite side of said supporting surface; an anchoring nut threaded on said second end of said body and engaged with said lock washer; a compression nut including means defining a seat and being threadably engaged with said first end of said main body; and a compression seal positioned between said seat of said compression nut and said seat on said first end of said main body, said compression seal in sealing engagement with said seat on said first end of the main body and said compression nut and the conduit so as to provide a fire impeding seal about the conduit.
