Recommended for open bore options

The GRB 35 is a 9" retaining-ball nozzle with a long tapered entry, two retention valleys, and a single 1.4" elliptical expansion ball. The tapered entry starts at 0.75" and gradually increases to 1" over 4.5". The first retention valley is 0.75", followed by the 1.4" expansion ball. Behind the ball, the body narrows to a 0.85" retention valley near the base.

Details

  • Overall length: 9" (22.86 cm)

  • Tapered entry: 4.5" long, starting at 0.75" (19.1 mm) and increasing to 1" (25.4 mm)

  • First retention valley: 0.75" (19.1 mm)

  • Expansion ball: 1.4" (35.6 mm)

  • Final retention valley: 0.85" (21.6 mm)

  • Base flange: 1.5" (38.1 mm)

Choosing your silicone firmness

For the GRB 35, Bob recommends #10 Medium. The firmer material gives the long tapered section and retention valleys more structure while still allowing the nozzle to flex.

Color options

#18 and #30 are available in pure translucent silicone.

#00-50 and #10 use a translucent white base and can be mixed with our standard colors.

Please note

The GRB 35 has a relatively narrow entry compared with its 1.4" expansion ball. It is a good choice for someone who wants a gradual entry followed by a larger single expansion and two distinct retention areas.

Anatomy varies, and no single size or shape will work for everyone. Use appropriate lubrication, never force insertion, and stop if you experience pain or significant discomfort. Inspect the nozzle before each use and do not use it if damaged.
