The OPW 634LPC Low Profile Top-Seal Fill Cap is designed for tight installations where the clearance between the top of the fill adapter 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 adapter groove for a water and vapor-tight seal. When engaged, the lockable cap adds only 1/2" to the final height of the adapter. The 634LPC can be used with the 4" OPW 633T, 633TE, 633TC, and 61SA series top-seal fill adapters.

The OPW 634TE is a Single Lever Action Top-Seal Cap designed to mate with 3" OPW 633T Top-Seal adapters. The locking lever seats in the groove in the adapter, providing a cam-down action on the cap for a positive water and vapor-tight seal. The 634TE can be locked with a padlock or wire seal.

Heavy duty and corrosion resistant, the body is made of Duratuff® to help eliminate rust and oxidation for a long, maintenance-free life. The toggle lever distributes downward pressure to compress its Buna-N gasket evenly, assuring a positive, water and vapor-tight seal. The 634TT can be locked with a padlock or wire seal.

The OPW 634TTM Well Cap Kit is designed to install onto a 4" slotted PVC monitoring well. The cap is marked "Do Not Fill" to clearly identify the monitoring well. A cast aluminum adapter ring is set-screwed to the top of the slotted PVC well, and the cap mates with the ring. The 634TTM can be locked with a padlock or a wire seal.
