Product Sourcing, Quality Suppliers of Hard to Find Items (PLEASE NO ADS!)

[ChrisN67]

I have reworked several boats and it has been a chore to find specific products. Can anyone help with the following"

1/4" MARINE GRADE stainless braided hydraulic line (Bulk) with stainless JIC Fittings? Similar in quality to mercury, but in bulk length for custom sizes.

Outdrive Bellows, this has been a source of frustration. I have a specific one-off application. Virtually no one lists dimensions, only part numbers. I need a very specific size and length. Almost impossible to find.

Hatch gasket material (oval profile) thick. I would like to use a double gasket material to seal engine hatches.

Quality 5" through transom wet exhaust. I tried 6" vetus but the flappers blew off when the diesels first fired. They look beautiful but the plastic flapper is a poor design.

Any help is appreciated
