This tethered rubber plug is a one-piece molded rubber part combining a sealing stopper and a flexible connecting strap with a retaining ring. It is specially designed to solve the common problem of lost plugs after disassembly. The retaining ring can be fixed around the fitting, so the cap stays attached and will not drop or get separated during use.

√ Integrated one-piece molding, no assembly required

√ Flexible rubber material, easy to insert and pull out

√ Built-in retaining loop for anti-loss function

√ Provides effective sealing against dust, water and debris

√ Custom dimensions, shapes and rubber materials available

The connecting strap maintains stable flexibility under repeated bending. The plug head fits tightly into matching holes or ports to keep contaminants out. It works well in mechanical equipment, hydraulic fittings, valve ports and various hardware assemblies. You can choose different rubber compounds according to your working environment, including oil resistance, high temperature resistance and weather resistance grades.

This anti-loss rubber stopper greatly reduces replacement costs caused by lost caps. We support custom mold development for non-standard sizes to match your exact installation requirements.
