leak-proof

Much variety is shown in the methods used to secure a leak proof joint between the posts and the cover.

The two rubber washers serve to make a leak proof joint between post and cover.

This forces the soft rubber washer tightly against the cover so as to make a leak proof joint-between the bushing and cover.

If it is not the container should be gone over again with solder to assure its being leak-proof.

Faith, but the County Cork would suit me completely; a roomy loose-box wid straw litter an' a leak-proof roof.
