SSND-JWW 7.5-9.5mm
- In stock, ready to ship
Recommended for open bore options
The SSND-JWW 7.5-9.5mm is a silicone urethral sound designed to dilate and stretch the distal sphincter situated near the urethral entrance. Moving away from long uniform shafts, the JWW architecture utilizes a short, tapered focal zone designed to provide targeted radial expansion right at the primary entry point. Ranging across precision diameters from 7.5 mm (22.5 Fr) to 9.5 mm (28.5 Fr), it offers a gradual, controlled step-up schedule for users looking to build internal flexibility. Cast in medical-grade platinum-cured silicone, it provides structural firmness without sacrificing anatomical comfort, and is available in both solid core and open-bore (hollow sound) configurations.
-
Entry Tip: Smoothly tapered leading tip designed for precise alignment and gentle initial entry.
-
Sphincter Focal Zone: Short, concentrated dilation profile providing targeted expansion at the outer urethral sphincter.
-
Shaft Diameter Steps: Available in precision step-ups: 7.5 mm (22.5 Fr), 8.0 mm (24 Fr), 8.5 mm (25.5 Fr), 9.0 mm (27 Fr), and 9.5 mm (28.5 Fr).
-
Retention Neck: Narrowed retention valley (5.75 mm – 7.7 mm) situated directly above the base to anchor the sound during wear.
-
Safety Flange: Broad flared base (12.8 mm – 17.3 mm) engineered to prevent over-insertion and allow easy, confident control.
Anatomical Depth Guide Featuring compact overall lengths of 60 mm (2.36") to 66 mm (2.60") and recommended insertable depths of 46 mm (1.81") to 50 mm (1.97"), the JWW series focuses strictly on entry-zone dilation. This truncated design delivers maximum expansion where it is needed most without placing length deeper in the urethral canal.

👑 Bob's Choice Recommendations
-
Experience Level: Beginner (Up to 11mm maximum diameter / targeted sphincter dilator)
-
The Prime Durometer Recommendation: We strongly recommend our #18 (Firm) or #10 (Medium) silicone density as the default primary choices. These firmnesses provides essential structural integrity, preventing the sound from bowing or buckling during insertion while delivering high-definition tactile feedback along the entry zone.
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.
⚠️ Important Safety Disclaimer: Because individual anatomy varies, we cannot guarantee a full fit for all longer or larger diameter pieces. Please use all products with care. By purchasing, you accept full responsibility for safe use. If you experience discomfort, discontinue use immediately.
