RatRig V-Core 4 / 4.x Printer Advanced Silicone Nozzle Wiper Upgrade

Upgrade your RatRig printer with a BenchRebel pure silicone nozzle wiper that replaces the common felt strip and alternative-mods for cleaner nozzles, more reliable first layers, and lower maintenance. Designed for serious makers and pros, this direct-fit wiper delivers consistent, repeatable nozzle cleaning without G-code tracks that look like a theme park roller coaster.

Compatible Models: V-Core 4 and V-Core 4.1

Features and benefits

• Direct replacement – No tools or adhesive required to install/swap this wiper into the common V-Core 4.x mount.
• Cleaner nozzle, better first layers – Reliably reduces blobs, stringing, and contamination that can ruin surface finish and first layer adhesion.
• Proprietary design – Variable, offset pattern, and angular features maximize wiper-to-nozzle contact with each pass, avoiding excessive or wasted movement during wipe operations.
• Reduced rebound (34%) – Increased rebound resilience eliminates harsh impact, eliminating vibration transmission into the toolhead.
• High elongation (230%) – Flexible, durable silicone resists tearing and deformation from repeated purge and wipe cycles.
• High-temperature capable – Built to handle demanding print jobs and extended runtimes with engineering filaments.
• Wide filament compatibility – Works reliably with stringy filaments like PLA and TPU, sticky filaments like PETG, and engineering materials like ABS, ASA, and Nylon.
• Probe-safe and non-conductive – Silicone construction is electrically non-conductive and safe for Beacon and Cartographer-style probes and other sensitive hardware.
• No G-code gymnastics – Drop-in, plug-and-play upgrade that supports simpler wipe and purge operations without custom macros (G-code gymnastics optional).
• Installs like OEM hardware – Simple, adhesive-free installation to match current V-Core 4.x workflow.

Why choose BenchRebel silicone wipers over alternatives?

• Protects your nozzles – Avoid scratches on brass and micro-abrasion on hardened steel nozzles caused by metal brushes.
• No metallic residue – Eliminates conductive debris that can accumulate on hardened steel nozzles and around the hotend area.
• No trimming or hacking required – Skip the trial-and-error of cutting metal brushes, PTFE tubes, or other wipers to fit; this wiper fits and performs out of the box.
