For dripping water the specification would need to be IP61

For protection against water when the product is at a 15 degree angle the specification would be IP62

To protect against sprayed water up to 60 degrees from vertical the specification would be IP63

To guard against splashed water from all angles you would specify IP64

Protects against water jets you would specify IP65

For protection when immersed in water for a defined time, depth <1m and pressure then you would specify IP66

There are many materials that can be used to manufacture High Quality Rubber Seals; therefore it is important to make clear the envisaged environment when requesting a quotation. One should consider; temperature extremes possible, any chemical or solvent contact, bio-compatibility, electrical and RF requirements, exposure to sun and UV. When designing a gasket in rubber, remember that the rubber does not squash on compression and reduce in volume, it merely deforms. This means that if you have a seal situation with a large area to seal against, it could require a high compression to get both faces to securely mate together. There are ways to deal with this problem, which can be overcome.

Rubber seals can be produced by extrusion methods, punched from sheet if the profile is flat, moulded by compression or injection methods. All of these methods require tooling and this can range from low cost for punch tools to higher costs for the moulding compression or injection tools. The best method is ultimately decided by the design of the part and the estimated quantities required. When designing the rubber gasket seal be aware that by making the profile too complicated this will not only effect the part cost but also effect largely the tooling costs, extravagant undercuts will mean a complicated tool design so try and keep these to a minimum. Ask your manufacturer for advice on solving your design issues, an experienced manufacturer should be able to advise what features are adding to the cost and suggest alternatives that may not previously been considered.
