PARKER® STANDARD MOLYTHANE MODULAR U-CUP BACK UPS

Modular back-ups, MB profile, are specifically designed to complement the PolyPak® profiles. To help make the selection and ordering of the correct part number for the MB profile easy and efficient, the part numbering system used is very similar to that of the PolyPak. By formulating high modulus blends of Molythane® (4617) and Polymyte® (4652), Parker® has ensured that MB back-ups can be used with either type of base sealing material while maintaining the expected temperature range and fluid compatibility. The robust design ensures pressure ratings up to 10,000 psi are met.
