Mosites Rubber Company

What Mosites Rubber Company does

Mosites Rubber Company is a privately held, Fort Worth, Texas-based manufacturer of industrial rubber sheet goods and custom fabricated rubber components. The company traces its origins to the late 1940s (firmographic year_founded 1947; one historical source cites 1948) and operates a single manufacturing facility at 2720 Tillar Street. Its product portfolio centers on two compound families — silicone rubber (commercial and high-strength grades, durometers 20-78, with specialty formulations including anti-static, electrically conductive, thermally conductive, and RTV adhesive variants) and fluoroelastomer/FKM rubber (premium and commercial grades, durometers 55-80, including FDA-compliant and military-specification products). Notable proprietary offerings include Mosites #651 hydroform rubber, the Mosites #1028 closed cell Viton® sponge, Mosites #2902 Aflas® compound, and the #10276 FKM pressure distribution pad.

The company's technology stack is rooted in rubber compounding and physical fabrication rather than software. Custom in-house formulations are paired with licensed raw material partnerships — Mosites is an authorized partner for Chemours' Viton® polymer and offers Asahi Glass's Aflas® — supporting service temperature ranges of approximately -80°F to +500°F depending on compound, with resistance to oils, fuels, solvents, and acids. Fabrication capabilities include silicone vacuum blankets, pressure bags and bladders, gaskets, seals, diaphragms, custom molded pads, composite materials (elastomers bonded to fabric or metal substrates), and a rubber pad repair service for metal forming customers. No AI/ML, public API, SDK, or mobile application is present.

Commercially, Mosites operates a direct-to-customer B2B model with quote-based pricing, same-day shipment on stocked silicone and fluoroelastomer roll goods, and 3-4 week lead times on custom fabrication orders. Revenue derives from one-time roll good sales plus custom fabrication and repair services for industrial buyers. Customer segmentation is vertical-based and spans aerospace and metal forming (primary), plus gasket supplies, automotive, composite manufacturing, circuit board manufacturing, environmental, cabinet manufacturing, energy, and food processing. International reach outside the US is achieved entirely through three channel distributors covering France, England, and Switzerland; no overseas subsidiaries or owned foreign sales offices are indicated.
