Flex Fittings, Flex Connectors, and Flexible Tubing - CMT Inc.

CMT offers white and black EPDM tubing flex sleeves among many other types of rubber tubings. EPDM (also known as ethylene propylene diene monomer) is a terpolymer of ethylene, propylene and a diene monomer, making EPDM flex connectors resistant to oxygen, ozone, and sunlight. EPDM Rubber flexible sleeves are excellent at handling acids, oxygenated solvents and wet or dry abrasive materials. This flex sleeve is suitable for outdoor exposure, as EPDM can withstand temperatures to 350°F.  It is resistant to polar materials such as phosphate esters, many ketones and alcohol. This type of rubber is a cost-effective alternative to silicone, as it can last for long periods of time with proper use. As a result, EPDM can save you time and money depending on the needs of your application. However, it must be noted that its resistance to petroleum products is poor.

CMT provides pure gum tubing for your specific application. Pure Gum Tubing Flex Sleeves are specially made for weather and ozone resistance. This flex sleeve has excellent tensile, elongation, tear resistance and resilience. It has good abrasion resistance and excellent low temperature flexibility. The flex sleeve has poor resistance to solvents and petroleum products. This flex sleeve is a best seller for dry materials processing. Gum rubber flexible sleeves have excellent abrasion and tear resistance.  The pure gum flexible sleeve is the most commonly used tubing utilized in practically every industry.

Nitrile rubber, also called nitrile-butadiene rubber (NBR, Buna-N), is a synthetic rubber that provides excellent resistance to petroleum-based oils as well as mineral and vegetable oil. Nitrile and BUNA-N tubing provided by Custom Advanced Connections can withstand a range of conditions in order to suit your specific application. Nitrile / BUNA-N is a copolymer of acrylonitrile and butadiene. It has excellent physical properties, however its claim to fame is based on its resistance to water, petroleum products and fuels. In the white formulation it is 3A rated. Useful temperature range is -40⪚ F to +220° F.

Nitrile rubber is far more resistant to heat and outdoor conditions, unlike pure gum rubber and other common rubber compounds. The heat and oil resistance of this material makes it a favorite among engineers and factory workers that deal with applications involving oil, fuel, chemical resistance, heat, abrasion, water, and gas. Nitrile rubber is also a great choice for applications that require abrasion resistance and metal adhesion.

Rubber Coated Nylon flex sleeves are an industry standard, but RCN is only one of many fabrics available to you. These light-weight sleeves are made with Neoprene and have a Nylon backing. Rubber Coated Nylon sleeves are very pliable, soft rubber coated on a two-way stretch nylon backing. RCN Sleeves feature sewn inside hems, shock cord is a very reliable elastic cord. Installed at 75% of the specified sleeve diameter, shock cord can be used to secure non-stressed sleeves to spout openings without the need for clamps or other fasteners.Popular uses include vibratory feeders, screw feeders, and other applications that involve load-cells where minimal impact is a must.

Our Silicone Flex Connectors create a highly flexible connection between batching equipment, mixers, loss-in-weight feeders, or any other type of process equipment on load cells involved in powder bulk solids transport. Accurate batch sizes and continuous material feeding are crucial to ensure a high quality end product. Silicone Flex Connectors are used by many well-known OEM manufacturers. Our Silicone Weighing Flex Connector features a molded flexible connection in FDA approved Translucent Silicone and Black Anti-Static Silicone. These flex connectors were specidically designed for use in weighing systems, as they have low axial and lateral force, and do not affect the weighing process.  The Black Anti-Static Silicone Connectors are made of a silicone compound to which carbon has been added to make it electrostatically dissipative and have a resistance lower than <10^6 Oh. The low electrostatic resistance results in preventing light powders from sticking on the surface of the flex connector, while preventing electrostatic energy from building up on the surface of the flex connector. This creates a safe factory environment, as explosion hazards (which may occur at high capacity powder flow rates and high air speeds) are limited.
