Seals

Find a wide range of sealing products from manufacturers, commercial and industrial seal distributors
By Robert Hill These companies won’t provide or design a corporate seal for your business. Their specialty focuses on sealing products for industrial, commercial and retail use. Designs vary to keep contaminants out, fluid and gases in and special sealing materials for extreme environments.

Types of seals include mechanical, hydraulic, pneumatic, O-rings and assorted rubber based seals. Each seal’s design fits a specific purpose for different fluids, hi or low-temperatures, pressure and contact material. When your business needs seals consider companies based on the following:

1. Select seals for industrial demands where heavy-duty and size matters.

2. Locate oil seals of every type that apply to your business requirements.

3. Choose rubber seals based on material and application.

4. Find specialty seals from distributors and seal manufacturers.

Locate industrial seals for your business

Industrial sealing products apply to a large application base.
Try:  For conduits and other industrial applications needing seal rings made of polyethylene, select seal rings by specific thread sizes at Sealcon. See Temper Corporation for high temperature seals ranging from 2 inches to 5 feet diameters. For tough sealing problems click “Products” to select business specific molded diaphragms at Dia-Com Corp. Go to Martin Fluid Power for piston, rod, rotary or seal kits.

Find specific oil seals

The shape or style of the oil seal determines function. For example, an "S" style offers sealing from severe grease, a "V" style design provides sealing of viscous fluids with other letter designations denoting various applications as well.

Material used to make rubber seals vary according to function. Buna-N for oil resistance, ethylene-propylene finds uses in water appliances and weather resistant environments, silicone for extreme temperatures, cast polyurethane for hydraulic pressure situations, neoprene for applications involving ammonia, and fluorocarbon finds use in engines and fuel systems.
