Founded in 1937, RectorSeal started as a manufacturer of specialty chemical sealants. One of our first products, RectorSeal Number 5, became a staple of the plumbing industry, becoming the most common thread sealant throughout the U.S. Since these beginnings, we have continued to grow by expanding our offering of chemical and mechanical products to support the tradesman in their work.

Today, Rectorseal has developed a robust line of chemical, mechanical and fire stopping products. These products are distributed through an extensive wholesale distribution network serving the plumbing, industrial, HVAC-Refrigeration, construction, electrical, and hardware market places. Their primary products include thread sealants, fire stopping sealants, plastic pipe cements, anti-seize compounds, fluxes, lubricants, chemical cleaners, duct sealants, leak locators, and other specialized products. Many of these products have built a strong following among contractors due to their differentiated performance and from being the first to tackle challenges faced by the professional trade.

CheckFlo Normal Open Back Water Valve

The Rectorseal CheckFlo backwater valve utilizes multiple magnets to create more secure seals, and hover the flapper above sediment in a way no other backwater valve can.

With a angled base and a smaller body the CheckFlo is faster and easter to install in the foundation. And with a 4" wide access cover it's fast to clean and ensure an unblocked pathway.

With three magnets on the flapper, base, and access, the back water valve is able to hover the flapper above any fluid and ensure faster seal when back flow begins.
