OATEY 14050 – Frequently Asked Questions

1) What pipe sizes does the Oatey 14050 Master Flash fit?
The Oatey 14050 Master Flash takes pipes from .25 in. to .75 in. in diameter. The EPDM collar is trimmed to the pipe size you're working with, so one part covers that whole small-diameter range, think small vents, conduit, refrigerant line sets, and sensor or cable penetrations rather than a full plumbing vent stack.
2) Will the Oatey 14050 roof flashing work on a metal roof with ribs, or only on a flat surface?
It is built for profiled roofing. The 14050 has a pliable base that conforms to corrugated and ribbed panels, and it works at any roof pitch, so it isn't limited to flat decks.
3) How do you install the Oatey 14050 Master Flash, and what do I need to buy with it?
Set the base in silicone sealant between the base and the roof surface, then fasten it down with sheet metal screws. Neither the sealant nor the screws come with the 14050, so add both to the order.
4) Can I use the Oatey 14050 Master Flash on a 2 inch plumbing vent stack?
No. The 14050 only covers .25 in. through .75 in. penetrations. For a 2 inch vent you need a larger Master Flash with a bigger collar and base, so pick the size range that brackets your actual pipe OD before ordering.
5) How much roof area does the Oatey 14050 base cover?
The base measures 4.5 x 4.5 inches, so it needs that much clear, reasonably flat panel area around the penetration for the sealant bed and the screw line. On a tightly ribbed panel, check that the rib spacing lets a 4.5 inch square base seat, otherwise step up to a larger Master Flash base.
6) I need to order the exact Oatey part number for a small conduit roof penetration, what is it?
Order Oatey part 14050, the Master Flash for .25 in. to .75 in. penetrations with a 4.5 x 4.5 in. base. It ships as a single piece weighing 0.021, with no size or finish options to specify.
7) Does the Oatey 14050 collar fade or crack after a few seasons in the sun?
The collar is non-fading EPDM, and the material is pliable so it won't crack or break with thermal movement of the pipe. That matters on a roof where the penetration expands and contracts daily.
