Rains-Flo Sealing System Sets have given many users a 300% increase
in packing and shaft/sleeve life, while greatly reducing leakage, when compared
to conventional braided packing. Rains-Flo Manufacturing, Inc.,
has been actively supplying the Sealing Systems to industrial customers since
Rains-Flo pre-cut Sealing Sets are a combination of GFM (Granulated, Flowable, Material) and carefully
chosen braided packings. This packing sets up into a
self-lubricating, bearing-like seal. Due to the nature of the solid structure
within GFM when the gland is tightened, the gland forces are transmitted to the
stuffing box base. These forces then activate the Rains-Flo braided collars at
the stuffing box base, which allows for sealing control to begin at that point.
Rains-Flo Sealing System Sets can significantly improve sealing performance,
give longer packing life, and have the exclusive "Add-A-Ring"
maintenance feature where packing is replenished instead of being readily
replaced. Rains-Flo Sealing System Sets can also dramatically reduce wear of
moving parts, and is comparably priced with braided packing.
The high lubricant content of the Rains-Flo GFM Packings
keep the braided collars from drying out, keeping them lubricated and
resilient. The GFM Packings are also heat conductive
rather than heat insulating like braided packing. A primary advantage of
Rains-Flo GFM type packing is, if overtightened, they will just increase lubrication rather than groove the
Rains-Flo pre-cut Packing Sets contain sufficient material to fill the
stuffing box, plus extra rings for later maintenance. A color-coded "Ring
Placement Diagram" is supplied with each set to insure proper
