3.2 Key Product Features
3.2.1 Fast Collar
The fast collar is designed to allow quick replacement of the flowtubes either
due to a requirement for a line size change or for repair. The fast collar is
released by unscrewing the collar from the connector sub, which bears
against the circlip to pull the seal out of the bore - allowing access to the flow
tube housing and the flow tube. This results in a fast and easy method of
configuring the greasehead and allows the injection and return ports to be
orientated as required.

3.2.2 Dual Ported Connector Sub
The Connector Subs between each of the flow tube housings has two
opposing saver sub ports. Depending on the Saver Sub fitted these can either
be blanked off or used for pressure monitoring in between each flow tube if
required. This provides maximum
operational flexibility
3.2.3 Check Valve Saver Sub
The saver sub interface also allows a right
angled check valve assembly to be used
that angles the outlet at a suitable angle
to ease the management of the hoses and
provides a check valve to prevent well
fluids being returned to the grease skid.
These subs can be placed in any location
but are normally used in the chemical
injection port and the grease injection
port.
The check valve components can easily be removed to provide a simple right
angled port that may be used on the grease return line if only one injection
line is required.
