Overview
Rubber stoppers are small but essential components that plug the open ends of garage door bottom weather seals and pneumatic safety edge gum hose. Without a stopper in place, a bottom seal can lose its shape inside the retainer, and a pneumatic sensing edge can lose the air pressure it needs to detect obstructions. In both cases, a missing or damaged stopper compromises the performance of the system it supports.
Barron Equipment carries rubber stoppers for two distinct applications — pneumatic reversing edge gum hose and Super Seal bottom weather seals. Each stopper is designed for a specific seal profile, so it is important to match the correct stopper to your system before ordering.
Gum Hose Stopper
The GHP-00-Z rubber stopper is designed for .50″ inner diameter gum hose used in pneumatic reversing edge systems on commercial and industrial garage doors. In a pneumatic safety edge, pressurized gum hose runs along the bottom of the door to detect obstructions. One end of the hose connects to the air switch via treadle hose, and the opposite end is sealed with this rubber stopper.
The stopper plugs the open end of the gum hose to retain the internal air pressure that makes the sensing edge system work. It also keeps out dirt, dust, and debris that could compromise the hose’s ability to compress and trigger the air switch. If the stopper is missing or damaged, the system cannot maintain pressure and may fail to detect obstructions in the door’s closing path.
Super Seal Bottom Seal Stoppers
The RST-05-W rubber stopper is designed for the Super Seal and Ultra EPDM T-end garage door bottom weather seals. After a bottom seal is installed in the retainer at the base of the door, rubber stoppers are inserted into the open ends of the seal to help it hold its U-shape when pressed against the garage floor.
Without end stoppers, the bottom seal can flatten or lose its profile at the edges of the door, creating gaps that allow leaves, debris, moisture, and pests to enter under the door. The synthetic rubber construction creates a tight seal at the ends of the weather strip, completing the barrier across the full width of the door.
Super Seal stoppers are available individually for single replacements or in a box of 24 for multi-door installations and service companies stocking inventory.
Available Options
- GHP-00-Z — Rubber stopper for .50″ ID gum hose on pneumatic reversing edges. Sold individually.
- RST-05-W — Rubber stopper for Super Seal / Ultra EPDM T-end bottom weather seals. Sold individually.
- RST-05-W-BX — Rubber stopper for Super Seal / Ultra EPDM T-end bottom weather seals. Box of 24.
Selection Assistance
These stoppers are not interchangeable. Each is designed for a specific seal type and profile. Before ordering, confirm which system you are working on.
If you are replacing or repairing a pneumatic safety edge on a commercial garage door, order the GHP-00-Z gum hose stopper. This is the same stopper included in the Action Industries Safety Edge Kit.
If you are installing or maintaining a Super Seal or Ultra EPDM bottom weather seal on a residential or commercial garage door, order the RST-05-W (individual) or RST-05-W-BX (box of 24). These are the same stoppers included in the Ultra Rubber EPDM Garage Door Bottom Seal Replacement Kit.
For single-door repairs, an individual stopper is all you need. For door service companies, property management, and multi-door commercial facilities, the box of 24 eliminates the need for repeated individual orders and ensures you always have stoppers on hand when installing or servicing bottom seals.
