This is a genuine OEM Coleman pump cup used with gas lanterns. This neoprene rubber part is used inside the air pump. The pump plunger fits through the hole in this pump cup, which then fits inside the pump itself. The pump cup is designed to be coated in Pump Lube so that it can effectively create a seal inside the pump, preventing air leaks. Pump Lube is sold as part # 200K2251. This part is sold individually.

very responsive to my order.
This was only a very small order in terms of monetary cost but ReplacementParts treated it as though it cost a fortune!. They are certainly the place I would use again for Coleman lantern parts or indeed anything else they carry
