Review on 🔴 50 Red Polyethylene Grease Fitting Caps: Protect and Seal Your Fittings with Ease by Edwin Cen

Finding well-made products in the supply chain is becoming increasingly difficult (this site is mainly dominated by Chinese manufacturers) but I have found protection caps zerk actually fit my tractor oilers. They've been in use for a month and I've noticed a red discoloration in the plastic which the old US made ones haven't seen in a year so I'm pretty sure they missed the UV protection. But they were 20% cheaper if the price is American, so with a 50-pack I might have spares for a few years.
