Sierra International Shields Multiflex 1-1/8" x 50' 16-141-1186B Shields Multiflex 1-1/8" x 50',

Strong, thick and also flexible. I used this product to replace all of my bilge lines.

Solid, no kink, clear so you can see fluid inside, and reasonably priced. I bought a 15' section from worstmarine and it cost more than this 50' box from Amazon. Great product at a great price.

Little pricey but it’s high-quality
