The OPW 634LPC Low Profile Top-Seal
Fill Cap is designed for tight installations
where the clearance between the top
of the fill adaptor and the underside of
the spill container cover is limited. The
rugged iron lever provides a positive
cam-action that seats the cap firmly
in the adaptor groove for a water and
vapor-tight seal. When engaged, the
lockable cap adds only 1/2" to the
final height of the adaptor. The 634LPC
can be used with the 4" OPW 633T,
633TE, 633TC, and 61SA
