  Product Description
Polyurethane Valve Petroleum & Natural Gas Industry Seals 
Description:
Polyurethane Valve Seals for Petroleum & Natural Gas Industry
These are polyurethane valve seals for the petroleum & natural gas industry. These seals are used in a harsh slurry environment of abrasive sand and water under high pressure. These seals are made of polyurethane because of its exceptional strength under high pressure and long wear under harsh conditions. 
Custom Polyurethane Parts For Petroleum, Natural Gas, Manufacturing and More
Our company creates custom polyurethane parts at low tooling costs for many industries including petroleum, natural gas, manufacturing, and the . All of these polyurethane components are designed to exacting standards. Each client project always begins with rapidly built prototypes created at low cost for evaluation and testing. We are happy to manufacture both short or long term product runs. 
Polyurethane Superior To Plastic, Metal and Rubber
Polyurethane component parts are used by the petroleum & natural gas industry because polyurethane is superior to other materials such as plastic, rubber and steel. Molded polyurethane parts offer high load and high compression abilities that function long after rubber and plastic parts have failed. Cast polyurethane parts can be made iron-strong or sponge-soft, in any color or shape. In addition, polyurethane components offer long run durability and extreme resistance to harsh environments of water, heat, solvents, chemicals and abrasion.
