About BrenLin Company
The Manufacturer of Seal-R™ Products
Family-owned and Operated Since 1998
BrenLin Company, Inc. is a family-owned and operated manufacturing business established in 1998 based in Herman, Minnesota.
We specialize in heavy-duty plastic septic system products and design all products in-house and manufacture them in the USA. Seal-R septic tank lids from BrenLin Company create a strong seal between the septic tank and the riser, eliminating water infiltration between the riser and the tank. They are made of durable materials, range from 12 to 42 inches, and can be personalized with a service provider’s company information. The 42-inch lid meets growing demand for bigger risers to accommodate new technology.
