plications.
Diagnostic products consist of a line of in-line diagnostic tees,

diagnostic products available fromParker’sQuickCouplingDivi-
sion and other mechanical pressure and temperature sensing
equipment. Some products can be used for fluid sampling and
bleeding purposes as well.
Parker offers a standard and custom line of fixed flow control
orifice fittings. These products are available as standard in two
Parker product series — ORFS and 37° flare, and as a custom
option in virtually any orifice size, fitting series, size, material
and configuration.
