Flexible Entry Boots
FlexWorks™ Flexible Entry Boots (EBF) are reliable, safe seals for pipe and conduit entries into underground containment sumps. These entry boots allow for angled pipe entries and have no exposed metal parts to the underground environment. These entry boots are available in a variety of sizes and designs to accommodate rigid and flexible piping, ducting and access pipe.
Flexible entry boots have been tested
to withstand a minimum of 6' of liquid
head pressure. These seals provide a
studded flange connection to create
a positive and secure seal where the
rubber contacts the sump wall and also
around the pipe or conduit. Tightening
down on a series of stud fasteners with
a compression ring provides a high compression mechanical seal compared
to screw-on-type bulkhead seals.
Primary pipe and access pipe entering the containment sumps may not be
perpendicular with the sump wall. Angled entries are generally a result of directional
plumbing restrictions on the inside of the containment chamber due to space
limitations. Flexible entry boots are flexible enough to permit angled pipe or conduit
entries (on two axes) into the sidewall of a containment chamber. All flexible entry
boots permit angled entries up to a 15-degree angle off the perpendicular center line
in any direction without leaking or putting undue stress on the pipe or conduit seal.
