Quick Product Summary
The Aladdin O-108-0 is a multi-use replacement O-ring used across a wide range of pool and spa equipment. Aladdin identifies O-108 for adapter, diffuser, dome-lid, valve, and volute sealing applications and publishes a broad cross-reference list covering Pentair, Sta-Rite / SwimQuip, Jacuzzi, Doughboy, Waterway, Premier, Aqua-Flo, and other manufacturers. Major Pentair references include 154493, 154494, 154495, 07-1422 / 071422, R18608, 211366, and 35505-1273. Aladdin also lists equipment families including WhisperFlo, Tagelus, Triton II, TR100C / TR140C, Rainbow 180, Sta-Rite, SwimQuip, Power Pak II, Flo-Master, and others. Since the same O-ring can serve different sealing locations depending on the equipment, verify the original OEM number and exact parts diagram rather than choosing by appearance alone.
Best For
- Replacing a documented Pentair 154493, 154494, 154495, or 35505-1273 O-ring
- Older WhisperFlo, Sta-Rite / SwimQuip, Tagelus, Triton, Rainbow, and related applications specifically calling for O-108
- Adapter, diffuser, dome-lid, valve, or volute sealing locations listed by Aladdin
- Technicians needing one verified cross-reference O-ring for multiple legacy equipment families
Why This Matters
- O-rings with similar diameters can differ enough in cross-section or fit to seal incorrectly.
- Matching the original OEM number reduces wrong-part orders across visually similar pump, filter, valve, and skimmer applications.
- A worn, flattened, cracked, stretched, or hardened O-ring can allow water leakage or air intrusion depending on the application.
- Aladdin's published dimensions provide another verification point when comparing the original seal.
Common Signs You Need This / Use This When
- The existing O-ring is cracked, flattened, stretched, hardened, cut, or missing.
- Your equipment parts diagram identifies Aladdin O-108 or a documented OEM cross-reference.
- A lid, valve, diffuser, adapter, or volute joint is no longer sealing correctly and O-108 is the specified ring.
- You are servicing an older WhisperFlo or Sta-Rite / SwimQuip application that specifically references 071422 or 35505-1273.

Compatibility / Fitment Notes
Aladdin publishes O-108 as a multi-use O-ring rather than a single-equipment seal. Its current cross-reference includes Pentair 154493, 154494, 154495, 07-1422, R18608, 211366, and 35505-1273; Jacuzzi 47-0256-06-R; Doughboy 308-1038 and 308-1099; Waterway 805-0256B; and other manufacturer references. Independent parts diagrams also identify O-108 with older WhisperFlo and Sta-Rite U-3 / SwimQuip applications. Do not assume every WhisperFlo, Tagelus, Triton, Sta-Rite, or other model uses this ring in every production revision. Match the OEM number and equipment diagram before purchase.
Installation / Use Notes
Shut down and isolate the equipment before service. If the O-ring is used on pressurized equipment, fully relieve pressure according to the manufacturer's instructions before disassembly. Remove the old ring, clean and inspect the groove and mating surfaces, and install O-108 without twisting, pinching, or overstretching it. Use only an O-ring lubricant approved for pool and spa equipment when appropriate. Reassemble according to the equipment manufacturer's instructions and inspect the repaired joint for proper sealing after startup.
Buy with Confidence
Benchmark Pool Supply helps customers identify replacement pool parts by manufacturer, equipment model, dimensions, and OEM cross-reference. Because O-108 is intentionally a multi-use O-ring, matching one of the documented part numbers or the exact equipment diagram is the best way to confirm fitment before ordering.
