Transparent rubber drain plugs
This two-pack supplies 45 mm rubber plugs designed for automotive and marine drain holes. The transparent material lets you confirm a seal at a glance. They are sold new and intended for interior care tasks where fluid containment is required.
Practical limits of rubber sealing
Rubber plugs rely on friction and material elasticity to stop leaks, so they work best in clean, round openings free of sharp edges. Over-tightening or exposure to aggressive solvents can degrade the seal over time. The plugs are not rated for pressurised systems or high-temperature exhaust paths.
Capacity and headroom for drain holes
Each plug covers a standard 45 mm opening, giving enough surface area to block typical floor-pan or transom drains. Two plugs handle a pair of holes on most small craft or vehicle floors. They will not span larger openings, irregular shapes or threaded ports that require a mechanical fastener.
