Review on 4424 Fisher Snowplows Style Pressure by Desmin Dickerson

Lines appear to be good quality for a replacement part. After installation, they leaked heavily at the junction of the cylinders (yes, they were tight). Even though they're NPT, I used some sort of pipe additive (tried without it - didn't help at all). The original lines sealed perfectly, so I just reused them (no sealant). I installed new side cylinders and forged 90 degree fittings (OEM NPT is correct for this plow) and also wanted new piping. These new lines sealed the pump perfectly. Installed on Fisher Unimount Pro models. Motor vehicle master from 1988 to today.
