What is included in the Best Fittings BSA Fill Probe Kit?
The standard kit includes the specific Best Fittings fill probe for your rifle model, two spare rubber O rings, and a small sachet of high quality silicone grease to keep the seals lubricated.
Can I connect this fill probe directly to my existing dive bottle or pump hose?
Yes. The probe features a standard 1/8″ BSP male thread, which allows it to screw directly into most standard UK flexible filling lines. Alternatively, it can be screwed straight into a Best Fittings Quick Coupler Plug if you use a quick disconnect snap-on setup.
Why is silicone grease included, and how should I use it?
The silicone grease is supplied to lubricate the probe's rubber O rings. Applying a tiny smear before inserting it into the rifle's fill port ensures a smooth fit, prevents the seals from tearing, and guarantees an airtight connection during charging.
Can I use standard automotive grease or oil on the probe or its seals?
No, never. You must only use the supplied silicone grease. Petroleum based oils or greases can degrade the rubber seals and, more importantly, pose a serious explosion hazard when subjected to the high pressure air used in PCP airguns.
