KIMAX ® Laboratory Glass Drain and Vent Systems

Kimax ® Drainline Systems are designed for gra vity flow. Borosilicate glass pipe and fittings are joined with bead-to-bead (B/B) and bead-to-plain end (B/P) compression couplings in diameters 1 1/2“ through 6“. Kimax ® glass piping systems are IAPMO Listed File # 0500. To view the IAPMO Listing Click Here .

Kimax ® products are manufactured to be durable with surprisingly high load bearing characteristics and superior chemical resistance compared to plastics and other alternatives. To view a short video demonstrating these features Click Here .

Kimax ® UL Classified Borosilicate glass conforms to ASTM Specification C 1053-90, Federal Specification DD-G-541-B, and Military Specification MIL-P-22561-B (YD) as manufactured by SCHOTT. Glass-to-glass connections shall be made with KIMAX compression type bead-to-bead and bead-to-plain end couplings – article numbers 6650 and 6661 respectively. Coupling’s outer shell, bolt and nut to be made from 300 series stainless steel. Bead-to-plain end coupling outer shell must encapsulate compression liner to prevent cold flow and ensure leak-free joint. Inner seal ring is made of tetra-fluoroethylene. System shall be installed in accordance with the manufacturer’s recommendations and the governing plumbing code.

Installing KIMAX ®

Safe– no off-gassing, field welding or fusing required

Simple– A socket wrench, butane torch and KIMAX glass cutter are the only tools you’ll need

Fast– With B/P coupling no field beading required. EVER!

Adaptable– Easily reconfigured to meet changing lab requirements and chemical compatibility needs

Cost Effective – fewer hangers, no expansion loops or joints, simple UL classified firewall penetration systems File No. R11306

Labor – Installation time required is approximately the same as no hub cast iron.

KIMAX ® Glass Drainline is the only low VOC emission piping system validated by UL Environment

The design and construction industries are experiencing dramatic changes led by the sustainability, or so called “green” building movement. With the help of programs like the U.S. Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) and the Department of Energy’s Labs21, these developments are transforming the marketplace and calling on everyone, from owners and architects to engineers and contractors, to make the ideas and practices of sustainable design the norm.


  • Lowest life-cycle costs on the market (installation, maintenance, replacement)
  • Modularity, flexibility, and adaptability in both design and maintenance
  • Easily reconfigured to meet changing lab requirements and chemical compatibility needs


Low VOC’s (Volatile Organic Compounds)

Water Conservation – No copious dilution required

Waste Water Treatment – on-site transport and neutralization of acids

Installer and lab occupant safety – no off-gassing of toxic fumes


Durability – maximum corrosion resistance and low relative thermal expansion

Dependability – maximum chemical compatibility in respect to temperature, concentration and intermixing

Will not burn or emit toxic fumes and no change in physical properties over time

Leak-proof mechanical joint couplings

No field welding or fusing required


Every laboratory and industrial DWV System is not only faced with the problem of transporting the acidic liquid wastes, but also how to store and dispose of these wastes as well. Since KOCH KNIGHT-WARE TM Acid Proof Chemical Stoneware Sumps have been used for over 80 years as the premium equipment in not only the handling and storage, but also the manufacture, of highly corrosive acids and chemicals it is the logical choice to handle such wastes. Partnered with KIMAX Glass Drainline it makes the most corrosive resistant DWV System on the market.

KNIGHT-WARE sumps provide positive and permanent insurance against acid and chemical attack. It does not depend upon a glaze or coating of any kind for its acid proof qualities – it’s in the body itself. Unlike some plastic sumps, which can be attacked by organic solvents which are normally present in laboratory wastes, KNIGHT-WARE is universally acid and corrosion proof regardless of the concentration of the acids handled. The only exceptions are hydrofluoric acid and strong caustic solutions.

Benefit of Material to Systems Application

Glass pipe is one of most corrosion resistant pipes available, which makes in a great choice for Chemical Waste Drainage. It will hold up to many chemicals that would eat away at many plastic or metal pipes, and will not give off toxic fumes when heated, which makes it one of very few materials allowed for use within a return air plenum. Glass Pipe will not burn, melt, soften, or sag when heated, and it has a higher operating temperature than plastic pipe. Glass pipe also has a very small thermal expansion coefficient, eliminating the need for expansion loops. Although glass piping is somewhat fragile, the mechanical connection used make replacement very quick and simple. These mechanical fittings also allow the pipes to be fitted at up to a 4° angle to one another, allowing for easier and less precise installation.

System Application and Material Usage

Chemical waste drainage systems require several components, including acid-resistant floor drains, neutralization tanks and pH monitoring devices. In cases where chemical neutralization is required prior to discharge into the sewer, the waste flow is directed to and collected in neutralization tanks containing limestone. In some situations, a double containment system may be desired or required. Consult current ASME standards for assembling these systems.

Chemical waste systems being routed through a return air plenum must meet the 20/50 flame spread and smoke development requirements of ASTM E84 or the more stringent flame propagation and smoke density requirements of UL910. Because of this requirement, glass piping remains the traditional piping of choice for acid waste piping with PVDF offered as an alternative.

Glass Pipe is used in most laboratory and industrial applications where the drainage system sees a wide variety of chemicals. In many applications it may be the only material that will hold up to the acids that will be flowing through the system. In applications where high heat or fire is a concern, glass pipe is almost always the material of choice. Glass pipe is available in 5 or 10 foot sections up to 12” in diameter.
