Core Tube Ring Seal 2".

Why are Wildco?corers so foolproof?One reason is the exclusive Ring Seal.This specially designed seal is used on all Wildco? 2?corers. It forms an airtight seal between the core head and tube and helps prevent leakage. A slight vacuum is essential to hold in samples; without it, you may lose material. This seal eliminates the need for pipe caulk or tape.
