Abstract
A check valve plunger assembly for use in a fluid channel is provided. The check valve plunger assembly includes a check valve plunger having a first end, a second end, and a body portion. The body portion extends between the first and second end of the check valve plunger. The plunger assembly also includes an integral breakaway retention device having a ring shaped portion. The retention device is capable of being positioned around the check valve plunger such that the ring shaped portion surrounds at least a portion of the first end of the check valve plunger. Breakaway connectors are provided which connect the first end of the check valve plunger with the ring shaped portion of the retention device. After assembly, the check valve plunger is separated from the breakaway connectors and the plunger is able to freely move within the fluid channel. The present invention also provides a method of inserting this check valve plunger within the fluid channel.
