Quick take
Super Lube silicone oil in a 4oz bottle — the shop-size lubricant for PCP O-rings and the right product for oiling PCP electric compressor internals. 16 orders. Same silicone chemistry as the 30ml product, just four times the volume — buy this if you own multiple PCPs, run a hand pump frequently, or own an electric compressor that needs internal lubrication.

The Hunt & Live take
Why this oil earns the pick
Same lubricant story as the 30ml — silicone oil is the right chemistry for PCP O-rings — but in the larger shop-size 4oz bottle for high-volume users. The partner specifically calls out PCP compressor oiling as a use case: electric PCP compressors need periodic internal lubrication, and the 30ml bottle runs out quickly when you’re maintaining a compressor.
Super Lube is the brand name — a long-established industrial silicone lubricant maker whose products are spec’d into machinery across many industries. The 4oz bottle is their standard small-shop size, and the same oil works for:
- PCP O-rings (drop on each ring during maintenance)
- Hand pump pistons (oil every 50-100 fills)
- Electric PCP compressor internals (per manufacturer’s lubrication schedule)
- Bottle O-rings (oil at each thread-on)
What it pairs with
- Hand pumps — pump piston maintenance
- PCP electric compressors — internal lubrication (check your compressor’s manual for schedule)
- Multi-rifle PCP household
- 100% Silicone Grease 15ml — complementary grease for static O-rings
Honest trade-offs
Too much for a single-rifle owner. If you only own one PCP and don’t run a hand pump frequently, the 30ml bottle is enough. The 4oz size will last 5-10 years for casual use.
No long applicator tip. Unlike the 30ml bottle (which has a long needle applicator for tight spots), the 4oz is a standard squeeze bottle. Decant a small amount into a precision applicator if you need to reach deep into a rifle.
Same chemistry, just more. Don’t expect different lubrication properties — this is the same silicone oil as the 30ml bottle, scaled up.
