AURUM MOUNT IND. CORP. established in 1981, major produce rubber expansion joints and flanges. Our rubber expansion joints and flanges, supplied quality material processed by skilled workers, turned our BYPRECISION machines and inspector by strict quality control, are of superior quality and reasonable price. ARMFLEX expansion joints are molded and vulcanized in hydraulic presses. This high-pressure process pro-duces a smooth finished product with outstanding adhesion between the cover, reinforcement and tube. Most of our competitors still use Natural Rubber impregnated Nylon tire cord between sulfur cured, Nature Rubber or EPDM plus Nature rubber covers and tubes. This construction becomes brittle with age at higher temperatures, so we changed Nylon to Polyester. Polyester has a higher modulus that swell and elongation, and outstanding temperature up to 240°F (115°C). Our ARMFLEX rubber joint use 100% EPDM as cover and tube, polyester reinforcement and middle special synthetic rubber. Our 100% EPDM Tube and Cover meet The Fluid Sealing Association Standard (FSA Standard). Most of other factory use Nature rubber or EPDM+Nature rubber as Tube and Cover can’t adhesive the middle rubber and easy separate at high temperature. ARMFLEX 100% EPDM full adhesive the middle rubber no separate at high temperature. Most factory use Nylon Fiber. We use Polyester fiber better then Nylon. Polyester better than Nylon fiber. We use synthetic rubber frication on polyester fiber. Nature rubber use at High temperature, the life time become short. AURUM MOUNT always supplies very good rubber joints.

Advantages
TEN ADVANTAGEOUS FEATURES OF USING ARMFLEX FLEXIBLE RUBBER JOINTS:
1. ABSORB VIBRATION, NOISE AND SHOCK
Sound, traveling axially through ARMFLEX Joins, is stopped at once. Water hammer, pumping impulses and water born noises are absorbed by the molded light-weight thin-wall structure.
2. EASY TO INSTALL, EASY TO REMOVE
Loose flanges, no need of gasket or packing, and elastic spherical body make the joint easy to install remove.
3. SECURITY ASSURED IN USAGE
Special spherical carcass enables its body, when subjected to high pressure and expansion, not contacting with the connecting bolt head. Thus, the joint may be used in a sense of damage proof and full security.

4. HIGHER BURST STRENGTH
Spherical shape is stronger than cylindrical shape or other configuration. Thus, under pressure, ARMFLEX Joint is 4 times as strong as a cylindrical joint. Additionally, our products are made of best suitable material, and hence their burst pressure is much higher than those of other makes.
5. SUITABLE FOR SUCTION AND DELIVERY (DISCHARGE)
Owning to its excellent molding technique with its tough chemical fiber, ARMFLEX Joint can satisfactorily withstand the suction and discharge. Vacuum rating can stand up to 750 mm Hg.
6. HIGH EFFICIENCY
ARMFLEX Joints has streamlined, flowing arch to reduce turbulence, sediment build-up, thrust area and the effects of thrust on the piping system equipment.
7. LOW DEFORMATION UNDER PRESSURE
Internal pressure is exerted in all directions distributing forces evenly over a large area. Hence, the deformation of ARMFLEX Joint due to pressure is much lower than that of other makers.
8. LIGHT AND COMPACT
The space required for the installation of ARMFLEX Joint is about half of the requirement of cylindrical. Weight is about one-third.
9.GREATER MOVEMENTS ARE AVAILABLE
Axial compression and elongation, deflection and angular movements will be greater.
10.WIDE SERVICE RANGE
Made with chemical resistant elastomers such as Neoprene, Nitrile, Hypalon. EPDM: insures a product compatible with the fluid being pumped or piped. Operate condition see our Temp V.S Pressure.
