Modular back-ups,Profile MB, are specifically designed to complement Polypaks and share a very similar part numbering system, making selection and ordering of the proper components easy and efficient.The robust design ensures pressure ratings are met up to 10,000 psi.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.
