Model B
Recommended for open bore options
The Model B is an advanced, 12-inch long nozzle engineered specifically for deep-fill efficiency and exceptional fluid control. Featuring a multi-stage profile with a prominent egg-shaped sealing bulb, this versatile piece can be utilized at two distinct depths. Position it near the entryway for stable rectal placement or gently advance it past the lower sigmoid sphincter to plant the main bulb directly inside the sigmoid flexure.
By delivering fluid straight into the lower sigmoid colon, the Model B completely bypasses the rectum. This localized delivery helps eliminate the sudden, early sensation of urgency or premature evacuation, providing a significantly more comfortable filling experience with unmatched control over cramping and internal contractions.
Anatomical Design & Dimensions:
-
Overall Length: A substantial 12.0" total length.
-
Tapered Guide Tip: Starts with a 2.0" long, 0.75" (3/4") diameter slightly tapered guide tip for a smooth, direct path.
-
Primary Egg-Shaped Bulb: Swells into a robust 1.875" (1 7/8") maximum diameter by 2.5" long sealing ball to anchor the piece securely in position.
-
Ribbed Mid-Shaft: Tapers down to a 1.2" shaft featuring three gently modulated ribs that measure approximately 1.4" at their widest points.
-
Secondary Sealing Ball: Swells back up to a 1.8" rear ball designed to nestle comfortably just inside the sphincter muscle to completely block fluid backflow.
-
Base Neck & Flange: Drops into a final 1.0" diameter valley before finishing with an external, gradually tapered 2.0" long by 1.9" wide safety flange to ensure perfect depth management.
š Bob's Choice Recommendations
-
Experience Level: Advanced. Due to its full 12" length and substantial 1.875" bulb diameter, the Model B is not recommended for beginners.
-
The Prime Durometer Recommendation: For a long-format piece with these unique dual-sealing zones, Bob highly recommends selecting #10. This softness level allows the long shaft to remain flexible enough to conform comfortably to the natural pathways of the lower sigmoid colon, while maintaining enough structural body to bypass muscle contractions smoothly.
-
The Ultra-Flexible Alternative: For users seeking maximum compression, flexibility, and an incredibly compliant feel under internal muscle pressure, Bob recommends ordering in our extra-soft #00-50 composition.
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.
