Video Transcript
The assembly of the four-component VCR assembly features a rotatable female nut or a rotatable male nut, a gland, a body with a fixed male VCR or a fixed female VCR, and a gasket.
The assembly instructions are the same for all VCR assemblies. Simply attach the male nut and the female nut finger tight. While holding the male nut steady with a backup wrench, tighten the female nut 1/8 of a turn. Tightening beyond 1/8 of a turn is not required.
A word of caution—you want to avoid connecting bodies with fixed male VCRs to bodies with fixed female VCRs. This could cause damage to the VCR bead, which could result in a leak.
Bodies with fixed male VCRs and fixed female VCRs should only be installed to glands with rotatable female nuts and rotatable male nuts.
