Product Advantages
Product Advantages
1. Press-In, Self-Sealing - Elastic compression holds the plug against the bore wall; tapered body adapts to slight diameter variation.
2. Waterproof & Leak-Proof - Blocks condensate, splash water and light pressure from escaping or entering through the opening.
3. Dust & Debris Protection - Caps off unused holes and pipe ends during storage, transport and installation.
4. Reusable, Not Consumable - Unlike tape or one-time caps, the plug can be removed and refitted many times - lower running cost for service teams.
5. No Tools, No Cure Time - Straight in, press firm, done. No adhesive waiting, no thread sealing tape.
6.Resistant & Durable - Rubber compound resists water, aging and repeated compression; stays elastic over long service.
Installation Instructions
Clean the opening - remove burrs, scale and old sealant residue.
Insert the smaller end first and press the plug straight into the bore. Press firmly until the plug seats flush or the flange contacts the surface.
To remove, pull or lever out from the edge - the plug is ready to reuse.
