O-ring Service Kit for High-Speed Ratchet Knobs™ RK-MW-SK MED-RAT-RK-MW-SK

O-ring Service Kit for High-Speed Ratchet Knobs™ Ensure optimal performance of your high-speed Ratchet Knob™ with our O-ring Service Kit! Our high-speed model is designed with O-rings. Over time the O-rings may break, or you may experience an increase in oscillation. When that happens, it’s time to replace the O-rings. The service kit includes a silicone-based grease/oil and 10 O-rings which will allow you to service your high-speed Ratchet Knob™ up to 5 times. To change O-rings:. Use a pick to remove old o-rings. Pre-lubricate new o-rings with silicone grease provided prior to installation. Starting at the corner, hold the o-ring in the groove and slide over the face of the lug until it fully seats into position. Repeat for the second side. If you feel it necessary at this stage, another application of grease to the outside of the o-ring is acceptable. Done! Continue to enjoy the use of your high-speed Knob. Get your kit today RK-MW-SK
