Quick verdict: LA Pump Elliptical Silicone Restriction Rings are most relevant to buyers comparing an oval opening with a round design. Their useful distinguishing feature is a detailed dimensional specification. However, neither an oval shape nor a size label establishes personal suitability. Our buying recommendation is to resolve fit questions before choosing an individual ring or a set.

What is different about the elliptical design?
The LA Pump listing specifies liquid silicone, a matte finish and three sizes. Its displayed price range is $8.95–$22.95 USD. The manufacturer describes the oval opening as offering a different fit from round rings; we have not independently tested that claim.
Elliptical ring size chart
| Option | Inner opening | Outer dimensions | Thickness |
|---|---|---|---|
| Small | 34.5 × 12 mm | 66 × 42 mm | 15 mm |
| Medium | 42 × 14 mm | 80 × 50 mm | 18 mm |
| Large | 48 × 16 mm | 92 × 56 mm | 20 mm |
These are seller-listed product measurements, not a personal fitting chart. The purchasing options include individual sizes and a set of three. Confirm the selected option and its current price in the merchant’s dropdown.
Why two opening measurements matter
An oval opening cannot be described adequately by one diameter. The longer and shorter axes both matter when comparing its geometry with another product. Do not read “34.5 mm” alone and assume the small oval ring has the same opening as a round ring of that diameter.
Calculated from the published figures, the long-to-short opening ratio is about 2.88 for small and 3.00 for medium and large. This shows that the openings are substantially elongated. It does not describe how the material behaves when stretched or how much pressure it applies.
Thickness changes too: the large model’s stated 20 mm thickness is about 33% greater than the small model’s 15 mm. That means moving between sizes changes more than opening dimensions. Without material testing, we cannot translate that difference into a comfort or firmness ranking.
Single ring or set: how to decide
An individual option makes more sense when you have already confirmed the appropriate model and size with reliable guidance. A set provides several supplied sizes, but buying three does not guarantee that one is suitable. It should not be treated as a substitute for fitting advice.
Compare the final selected-option price, shipping and return terms. The price range alone does not establish the price of each size or prove a bundle saving. Avoid buying extra sizes solely because the set appears inexpensive.
Elliptical versus winged rings
The oval product’s comparison point is its two-axis opening and stated thickness. The winged model has a different outline and lists a single inner diameter per size. Read our Winged Silicone Restriction Rings review for its dimensions. Size names such as “small” are not a standardized match between these designs.
Questions to settle before ordering
- Ask LA Pump support which measurements and fitting instructions apply to this exact product.
- Confirm lubricant compatibility and the supplied use, removal and care instructions.
- Check the merchant’s purchase terms for this accessory rather than assuming cylinder return rules apply.
The seller specifies mild soap and warm water for cleaning, followed by complete drying. Follow the supplied instructions. If you are considering a restriction device for a medical condition, ask a qualified clinician about suitability; this review does not establish treatment effectiveness.
Frequently asked questions
Is the inner opening round?
No. It is specified using two dimensions. Comparing only the longer axis with a round diameter misses the shape difference.
Does “large” mean the same size across LA Pump ring designs?
No. Compare the exact product measurements and fitting guidance, not the size label alone.
Does the listed price include all three rings?
The page offers both individual sizes and a set. Check the selected variation; the displayed range covers multiple options.
Final assessment
This product offers a clearly documented geometry to compare, which is more useful than a generic comfort claim. Its unresolved questions are personal fit and material behavior. Confirm those before buying; we cannot justify a star rating or a claim that the oval shape is universally better.
