New Hyde Park, NY -- These slit type plastic couplings from Sterling Instrument (An AS9100 Registered Manufacturer) features low cost, UV resistance, voltage and RF isolation. These couplings, identified as the S50TLC... Inch Series are stocked in sizes 13, 19 and 25. This lightweight molded patented coupling can replace stainless/aluminum slit type couplings with low cost and improved operation. There is no windup or backlash or any derating for reversing applications. To insure a tight fit between the shaft and the coupling, a metal screw-to-metal nut design is used and does not utilize threads cut into the molded piece.

These couplings are made of engineered polymer and have stainless steel fasteners. Their bore sizes range from .125" to .500" (from 3 mm to 12 mm). They range in length from .710" to 1.400" (18 mm to 36 mm). Their maximum temperature range is -4°F to +284°F (-20°C to+140°C).
