About Us

From the start in southern California, through two decades in Reno, Nevada, and now from a new facility in Tampa, Florida, Bulldog has earned a reputation for excellence.  Bulldog has always focused on high quality products, industry leading technical support, and friendly customer service.  With this focus, Bulldog Brand products have been engineered with special attention to the proper selection of materials, the development of exacting manufacturing standards, and the delivery of consistent product quality.  Bulldog Engineering has in-depth knowledge of the sealing applications employed in many types of mobile equipment.  This experience supports Bulldog’s catalog products and provides customers with solutions to their most demanding sealing applications.  Bulldog’s dedicated customer service team pulls it all together and schedules production operations to support partners with the products they need, when they need them.


In 2001, Bulldog was purchased by the Hercules Fluid Power Group.  Being part of this group has brought many benefits and Bulldog has grown tremendously during these years.  Manufacturing capabilities have been expanded to include several pieces of CNC-operated gasket manufacturing equipment, giving the capacity for high-volume production along with the tools necessary to produce gaskets for custom and low-volume applications.  Inventory and product availability have broadened and now include over 11,000 items, all in-stock and immediately available.  Kit assembly and packaging has been upgraded and automated to improve product presentation and provide for quicker delivery.  Even non-standard and special-order items can be easily developed and integrated into the systems for rapid support of all customer demands.


Beginning in 2012, Bulldog’s sales team was expanded with the support of its sister companies.  In the US and Latin America, Hercules Sealing Products now supports and fulfills orders for the Bulldog Brand products from their office in Clearwater, Florida.  In Canada, Bulldog Brand products are supported and locally stocked by Hercules Sealing Products-Canada, in both the Barrie, Ontario and Dorval, Quebec locations.  Internationally, the teams at FPE Seals Ltd (UK) and FPE Seals BV (Netherlands) provide support to markets outside of the Americas.  The addition of these sales teams has greatly improved customer support and enhanced Bulldog’s partnership with its worldwide customers.  As in the past, Bulldog’s agents continue to support the team effort in select markets around the globe.  As an example, Patriot Engineering Services continues to support Bulldog partners in the Middle East by enhancing the promotion of Bulldog Brand products with end users and streamlining the logistics surrounding product delivery to this region.


In September 2015, Bulldog relocated to a new facility in Tampa, Florida.  The new facility, located at 8711 Florida Mining Boulevard, features almost 36,000 ft2 of warehouse/production space and 3,500 ft2 of office space.  The benefits of this new facility are being quickly recognized.  From the dock layouts to the 24’ ceiling clearance, the facility itself has allowed Bulldog to structure its product and process flows in ways unavailable in the past.  This new layout immediately improved process throughput and reduced the effort involved in even the simplest tasks.  In addition, much of the old, inefficient equipment has been upgraded with new technology that is more supportive of modern day production and distribution needs.  The information technology structure was also reimagined for improved internal productivity, matched with a partner system for redundancy in case of emergency, and connected to the outside world with high-speed fiber-optic data lines.  With this new facility, layout, and equipment, Bulldog is now fulfilling orders more quickly and efficiently than in the past.  Outside of the facility itself, the new Florida location provides benefits of its own.  It is only minutes from both FedEx and UPS facilities, providing for convenient parcel shipments to customers.  It is also only a short drive from Hercules Sealing Products (Clearwater, FL) which allows for prompt replenishment of the stock supporting Bulldog’s US customers.  Finally, with a large volume of product exported outside the US, the new proximity to east coast shipping points has shortened transit times and reduced logistics costs for many of Bulldog’s international customers.


Also during 2015, Bulldog continued to expand its product line and announced several significant additions to its hydraulic and gasket product lines.  Hydraulic seal kits were developed for the service and repair of CAT® 400 series loader-backhoes along with updates to many service products for CAT® scraper, skidder, and pipe-layer equipment.  Of particular note are Bulldog’s new engine overhaul kits.  Based on customer feedback and inquiries, Bulldog has developed engine gasket overhaul kits in support of Deere® equipment, namely the 2.9PT, 4.5PT, and 6.9PT engine series.  Bulldog has also recently released overhaul kits for Komatsu® 6D95 engines.  Market response to these new products has been strong and Bulldog plans additional products supporting these and other equipment brands in the future.


While many things have changed, Bulldog remains committed to the same long-standing goals—providing high quality products with unmatched customer service.  With the new facility, Bulldog is set to build on its long history of excellence and looks forward to continuing its support of customers.
