KAN-therm: Connectors



Connectors

System KAN-therm Groove fittings and couplings are used in HVAC installations as well as in the industrial and fire protection installations. Thanks to the use of the highest quality ductile iron, they are characterized by high resistance to temperature and working pressure. Depending on the needs of a given investment, the couplings are available in various structures:

Rigid and high-strength rigid coupling

Gasket materials

EPDM (Ethylene Propylene Diene Monomer)


EPDM


The EPDM compound is considered the most waterproof, currently available elastomer. Gaskets made of this type of material are most often used in systems such as cold and hot water up to 110°C, waste water, water with acid, deionized water and sea water. EPDM compound is not suitable for use with petroleum-based fuels and oils, hydrocarbon solvents and aromatic hydrocarbons.

Compound Grade Colour code Recommendations for use Maximum range of temperature

EPDM E


Green strap

Suitable for cold and hot water up to + 110°C, a mixture of water and acid, chlorine water, deionized water, seawater and sewage water as well as diluted acids and compressed air without oil content. Do not use with petroleum oils, mineral oils, solvents and aromatic hydrocarbons.

From -34°C
To +110°C


Warning! EPDM rubber gaskets intended for water supply services are not recommended for use in steam systems, unless the connectors or components are in places allowing for frequent gasket replacement. Incorrect selection of the gasket and mixture may result in a leakage or failure leading to personal or property damage. Gaskets should never be exposed to temperatures above rated values.

NBR, BUNA N and nitrile

They all represent the same copolymer of butadiene and acrylonitrile (ACN) which is inherently resistant to hydraulic fluids, lubricating oils, gear oils and other non-polar petroleum based compounds as well as water at temperature not exceeding 65°C. NBR has low resistance to hot water and steam.

The "T"-type NBR compound is manufactured based on ASTM D2000 standard and exceeds AWWA C606 standard. Type "T" is a general-purpose compound with an average ACN level

Types of gaskets

Proper selection of gaskets is essential for optimum performance of grooved couplings, flange adapters and saddle connectors.

System KAN-therm Groove couplings are used with various types of gaskets: standard, Gap Seal (slotted), EP (with end-protection) and FF (quick-release). Gap Seal gaskets are compatible with standard gaskets and can be used interchangeably. Always use gaskets that match the selected coupling model.

Standard gaskets ensure effective sealing under vacuum conditions up to 0.34 bar which can occur during emptying the system. In the case of continuous operation, with pressure lower than 0.34 bar, it is recommended to use EP gaskets (with end-protection) in combination with rigid couplings. For specific recommendations, please contact with KAN technical department.

For dry fire-protection systems and cooling applications, it is recommended to use Gap Seal type "E" gaskets which closes off the gap between the pipes or gasket cavity. This will prevent any remaining liquid from entering the cavities and freezing when the temperature drops. Rigid couplings are preferred for dry pipe, freezer and vacuum applications. Reducing couplings are not recommended for these applications.

NOTE! In the case of dry and cooling systems do not use standard grease. Instead, it is recommended to use a silicone-based grease that does not contain petroleum.


To prevent pinching (damaging) the gasket, it is recommended to use during assembly a lubricant available in the KAN-therm Groove offer. It is enough to apply a thin layer of grease to the outer wall of the gasket, lip of the gasket and/or the inside of the casing of the sealed element. Grease is available in containers with a capacity of 450 or 900 grams. It has NSF/ANSI 61 certificate.

Detailed information on the type of gaskets and their applications is available in the System
KAN-therm Groove Catalogue.
