AquaStar 8-Inch Retrofit MoFlow Suction Cover with Adapter and Screw Kit, Light Gray | R8MF103

One light gray retrofit MoFlow cover, two round retrofit suction outlet adapters and four pairs of 316 stainless steel screws: two #10 × ¾-inch flat-head Phillips, two #10 × 1-inch flat-head Phillips, two #8 × ⅝-inch pan-head Phillips and two 10-24 × ½-inch flat-head machine screws. Not all hardware is used for every installation. No mud frame is included.

AquaStar identifies the R8MF family for specified off-standard 8-inch frames with 7-13/32-inch, 6-inch or 4¾-inch center-to-center mounting measurements. Match the actual frame, mounting hardware, sump and certified flow requirements. The nominal 8-inch family name alone does not establish fit.

Standard 8MF uses the 7-inch mounting pattern and includes a mud frame. R8MF is a separate retrofit cover and adapter/hardware kit for the specified off-standard patterns; AquaStar expressly states that it does not include a mud frame.

The 2026 guide lists R8MF as a current option for the off-standard 8-inch retrofit group that includes R8HP and RLP8AV. Confirm the exact existing frame, screw pattern, sump geometry and adequate certified flow rating; this is conditional replacement guidance.

AquaStar specifies a UV-resistant engineered polymer cover and 316 stainless steel mounting screws. Follow the manufacturer’s maintenance and replacement requirements for all assembly components.

Use the exact R8MF SOFA configuration in the manufacturer document revised April 2, 2024. For example, the specified floor configuration with 2-inch bottom plumbing and a 3-inch minimum pipe depth is listed at 106 GPM, subject to the document’s complete flow-path geometry and installation conditions. Do not select a rating from cover or pipe size alone.

The current catalog identifies R8MF as certified to NSF/ANSI/CAN 50 and ANSI/APSP/ICC-16 2017. Match the actual product markings and manufacturing generation to the corresponding documents. AquaStar directs post-May 24, 2021 production to its VGBA 2017 files.

No. The catalog’s 32-per-case notation is the manufacturer outer-case reference. This listing supplies one cover with its retrofit adapters and listed screw kit.

The 2026 catalog identifies ProStar SCW004 for R8MF: two RLPA retrofit adapters and the four pairs of mounting screws listed for the cover kit. That replacement hardware kit is sold separately. Use only approved components and select the correct fasteners for the actual frame.

AquaStar’s IN021-062724 instructions require replacement of the cover assembly and fasteners within five years of installation, or earlier if damaged. Service life begins when installed, with or without water. Inspect the adapters, frame and other components and follow all manufacturer maintenance requirements.

R8MF is a blockable suction outlet configuration. New pools and spas require a multiple-SOFA system. Existing single-outlet systems also require an appropriate additional anti-entrapment device or system described in the instructions. Have a qualified pool professional verify the complete installation.

AquaStar’s 2026 catalog states a general one-year limited warranty from original installation for defects in materials and workmanship, subject to the complete terms and exclusions. Color fading, improper installation, poor water chemistry and other listed causes are excluded; non-approved components may void coverage. Repair or replacement is at AquaStar’s option. Read the manufacturer’s catalog limited warranty, printed page 238. A drain cover’s required replacement interval is a separate matter.
