The OPW 634TT is designed to mate
with 4" 633T, 633TE, 61SA, 633TC, and
633TCP Top-Seal Adaptors. Heavy duty
and corrosion resistant, the body is
made of Duratuff® to help eliminate rust
and oxidation for a long, maintenancefree
life. The toggle lever distributes
downward pressure to compress its
Buna-N gasket evenly, ensuring a
positive, water and vapor-tight seal.
The 634TT can be locked with a
padlock or wire seal.
The OPW 633TE adaptor is similar to
the 633T, except it does not have
internal wrenching lugs.
