Apparatus and methods for supporting conduits within a sanitary environment. Some supports are configured so as to avoid the formation of surfaces that might collect dust, debris, cleaning fluids, etc. when installed. In one embodiment, the support includes a pair of opposing support members that may be releasably and sealingly secured together. The upper support member may have a substantially uninterrupted convex surface that has a desired texture. The lower support member may be sized and shaped such that no portion thereof protrudes outwardly beyond the upper member to form any surfaces, pockets, etc. wherein dirt, debris, cleaning fluids, etc. may accumulate. A seal or grommet may be employed to establish a seal between the conduit and support to prevent the infiltration of dirt, debris, cleaning fluids, etc., between the conduit and the conduit support. The fasteners may be employed to couple the first and second support members together may be dimensioned so that their outer edges do not protrude laterally beyond the outer surface of the upper support member. The upper support member may have an installation area near its apex where a support member can be sealingly affixed for mounting the conduit support to a support structure.
