With over two decades of experience and a knowledgeable team of technicians, Polymer Molding Inc., manufactures high-quality plastic caps, plugs and custom moldings. Our products protect threaded fittings, tubing and valves from contamination and shipping damages. We primarily work with commodity-grade resins, and also have substantial experience working with engineering-grade resins. In addition, we manufacture custom orders in a variety of materials, including resins with thermoplastic and thermoset capabilities. For custom orders, we also offer engineering assistance, colour matching, insert molding, and numerous secondary operations that include bagging, hole punching and printing. With same-day shipping and cost-effective pricing, we are committed to putting the customer first.

Plugs Product Line

We manufacture twelve models of plugs to suit any need that you might have. The tapered-style plug, which can also be used as a cap, protects pipes, valves and other cylindrical openings from contamination. Similar in design to the tapered-style plug, the pull plug also includes a pull-tab on top of the flange. The flare-fitting plug is designed for flared JIC fittings, and features a positive seal for low-pressure environments. For a sleek flush finish, look into the push-in plug. We also manufacture sheet metal plugs for thinner materials, silicone pull plugs for “through-hole” applications, and tubing inserts in a wide range of shapes and gauges. These plugs are primarily made of low-density polyethylene.

Plugs Industrial Applications

Our customers work in the automotive, aerospace, construction and fluid power industries, among many others.
