These silicone rubber round plug end caps provide a clean, tool-free solution that seals PVC pipe ends and fitting sockets in seconds, keeping systems protected during installation, testing, and storage.\u003c\/p\u003e\n    \u003cp\u003eEach plug is molded from flexible silicone rubber, which compresses and conforms to the pipe or fitting bore for a snug, removable seal. The round plug profile suits both pipe OD (for pipe-end capping) and fitting socket ID (for connector port sealing). Available sizes cover PVC40 through PVC200 pipe series and their corresponding connector sockets, with actual diameters ranging from 36.3mm (~1-7\/16\") up to 191.5mm (~7-1\/2\") — see variant options for the exact diameter that matches your pipe or fitting.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include capping unused irrigation manifold ports, sealing PVC conduit ends during construction, pressure-testing closed pipe sections, and protecting stored pipe fittings from dust and moisture. Long-tail use cases such as \"PVC pipe end cap silicone plug 110mm\" and \"rubber hole plug for PVC fittings\" are directly addressed by this product's broad size range.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits PVC40, PVC50, PVC75, PVC110, PVC160, and PVC200 series pipes and connectors.
