OF 1.6

The OF 1.6 is a beautifully engineered small-to-medium-sized nozzle featuring a specialized, body-contoured oval base flange. Sharing a sleek, gradual taper aesthetic with our SPD 1.6 model, the OF 1.6 is uniquely optimized for prolonged, hands-free comfort. The elongated base is intentionally contoured to nestle smoothly against the gluteal cleft, while a secondary flair just ahead of the flange provides secure, multi-stage retention points at varying depths.

With a gentle profile that expands to a satisfying 1.6" midpoint before stepping down into secondary anchor zones, this nozzle provides an incredibly reliable, leak-free fluid seal for intermediate users.

Anatomical Design & Dimensions:

• Overall Length: 6.0" total length.

• Insertable Length: Allows up to 5.5” of comfortable, fully insertable depth.

• Narrow Rounded Tip: Starts at a slim 0.5” (12.7mm) diameter for an exceptionally smooth, low-pressure entry.

• Main Taper Max Diameter: Gradually swells up to a maximum diameter of approximately 1.6” (40.6mm) to form the primary seal.

• Primary Retention Valley: Gently drops back down to a 0.95” (24.1mm) diameter neck.

• Secondary Retention Swell: Features an immediate secondary flair of approximately 1.0” (25.4mm) diameter to allow secure positioning at an alternative depth.

• Final Base Neck: Tapers down to a slim 0.7” (17mm) final valley right before the base to eliminate muscle strain.

• Contoured Oval Flange: Measures a low-profile 0.9” by 3.0” wide, designed to sit flush against the body and not intended for insertion.

👑 Bob's Choice Recommendations

• Experience Level: Intermediate. The OF 1.6 bridges the gap perfectly between introductory sizing and advanced retention. It is an excellent step-up choice for intermediate users looking for a wider profile without a deep insertion length.

• The Prime Durometer Recommendation: For this specific model, Bob recommends choosing #10. This firmness level allows the 1.6" maximum taper to remain pliable and easy to place, while keeping the specialized oval base firm enough to hold its comfortable, contoured shape against the body.

• The Extra-Support Alternative: If you are configuring this piece as a solid-core retention plug and want maximum resistance that won't compress under heavy muscle pressure, Bob recommends stepping up to #18.

Color Options: #18 and #30 are available in pure translucent. #00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.
