AP Diving Silicone Grease
This high-quality food-grade silicone grease offers excellent lubrication and durability under all conditions, especially for rebreathers and scuba equipment.
Note: For best results, XR Scuba recommends you use this grease sparingly, especially in areas where O-rings are exposed to the environment (such as your rebreather hoses and mouthpiece). Too much grease will attract contaminants which may cause leaks and/or increase your maintenance requirements.
Caution! Do not use silicone grease on oxygen fittings. Use oxygen-compatible grease.
