RetroArms Hop-Up Nub Set – Type A

RetroArms Hop-Up Nub Set – Type A
The set is designed for standard and CNC hop-up units from various manufacturers. The silicone nub provides full contact pressure, while the hollow PTFE nub offers different characteristics when adjusting the hop-up. Both nubs are resistant to oils and greases. During installation, we recommend lightly securing the nub to the pressure arm with grease to prevent it from falling into the hop-up unit during assembly.
Key Features

2 Types of Nubs
The set contains a solid silicone and a hollow PTFE nub, allowing you to choose a suitable option for your particular hop-up setup.

60 ShA Silicone Nub
The solid nub made of silicone with a hardness of 60 ShA is suitable for use in both standard and CNC hop-up units.

Hollow PTFE Nub
The second nub is made of PTFE and features a hollow construction.

Same Width as the Pressure Arm
The nubs have the same width as the pressure arms of hop-up units, which helps reduce their deformation when adjusting the hop-up pressure.

Resistant to Lubricants
Both nubs are resistant to oils and greases. During installation, the nub can be lightly secured to the pressure arm with grease.
