Item No. RGS-017
Our rubber plug with metal pull hook is designed for industrial sealing and hole‑blocking applications. The main body is solid round rubber, delivering outstanding elasticity, compression resistance and heat resistance to maintain stable sealing under high‑temperature working conditions.
A heavy‑duty U‑shape metal pull hook is firmly embedded on the top surface. This special pull‑hook design allows operators to pull the plug out effortlessly, no extra tools required for mounting or demounting. It can be repeatedly inserted and pulled out for long‑term reuse.
Firm sealing performance prevents leakage, dust and debris from entering pipe ports or equipment holes. Widely applicable for pipe sealing, machinery port plugging, tank hole blocking and other industrial environments. Custom sizes are available upon request to match different hole diameters.
Key Features :
1. Embedded U‑shaped metal pull hook : Firmly integrated metal hook for effortless plug removal, no extra tools needed for mounting and demounting.
2. Solid round rubber body : Robust one‑piece rubber construction, good compression resistance and long service life.
3. Excellent sealing performance : High elasticity ensures tight fit inside holes or pipe ports to block dust, liquid and leakage.
4. High temperature resistance : Stable performance under high‑temperature working conditions, suitable for harsh industrial environments.
5. Reusable design : Can be inserted and pulled out repeatedly without losing sealing capability.
6. Wide compatibility : Ideal for sealing pipe openings, machinery holes, tank ports and other industrial or equipment orifices.
7. Customizable dimensions : Multiple sizes available, custom diameters can be offered to match different hole sizes.
Applications :
1. Pipe port sealing : Block openings of pipes during testing, cleaning and transportation.
2. Industrial machinery hole plugging : Seal unused or temporary holes on mechanical equipment.
3. Tank & vessel orifice blocking : Close small holes on tanks, containers and pressure vessels.
4. Powder‑coating / painting masking : Mask holes to avoid paint over‑spray in surface‑treatment processes.
5. Equipment testing & trial operation : Temporarily seal ports for pressure‑testing and commissioning.
6. Automotive industry : For temporary hole sealing of castings and components.
7. Chemical & thermal processing : Suitable for high‑temperature working conditions in thermal‑processing equipment.
8. General‑purpose temporary sealing : Reusable plug for production, storage and transit protection.

Standard: Goods are typically supplied in about 20-25kg/carton.
Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
What is the function of the metal pull hook?
The embedded U‑shaped metal pull hook allows quick and tool‑free removal of the rubber plug. Operators can pull the plug out easily for inspection, maintenance or disassembly, greatly improving working efficiency.
What temperature range can this rubber plug withstand?
Our rubber plug features good high‑temperature resistance. It keeps stable sealing performance under high‑temperature industrial conditions. Exact temperature resistance depends on material formula; please contact us if you need specific temperature parameter data.
Is this rubber plug reusable?
Yes. It adopts solid rubber structure with excellent elasticity and compression resistance. It can be repeatedly inserted and pulled out without easy deformation for long‑term reuse.
What applications is this plug suitable for?
It is widely used for temporary sealing of pipe ports, machinery holes, tank openings. Also ideal for hole masking during painting/powder coating, pressure testing, equipment commissioning and transit protection.
Can you supply custom sizes?
Yes. Multiple standard sizes are in stock. Custom diameters and thicknesses are available according to your drawings or actual hole dimension requirements. OEM orders are acceptable.
Will the metal hook fall off from the rubber plug?
The U‑shaped metal hook is firmly embedded into rubber during molding process. Under normal working conditions, it will not detach. Excessive violent pulling should be avoided.
Does it work for liquid‑tight sealing?
It provides reliable sealing for blocking dust, debris and low‑pressure liquid. Not recommended for high‑pressure continuous liquid‑holding scenarios. Please tell us your working pressure for proper model selection.
What material options are available?
Main material can be ordinary rubber or silicone rubber. Silicone version delivers better high‑temperature performance. Please inform us of your working environment for material recommendation.
