Daemar's O-ring Pack Program provides AS-568 size o-rings packaged in quantities ranging from 5, 10 or 20 rings per pack. Sizes, quantity and a bar code are all printed on the poly bag.
Back-up rings are washer-like devices that are used to prevent a seal from extruding through any gaps while under pressure. These seals are installed in the downstream side of the gland. Back-up rings are not seals themselves, but are usually used in conjunction with O-rings in high-pressure applications (over 1500 psi) for support or as spacers.
