CONNECTION TYPES
MEDIUM PRESSURE (MP)
• Industry standard connection for 20,000 psi (1400 bar) applications, medium
pressure is occasionally used in applications at 15,000 psi (1000 bar) and
below.
• Connections exist in two different forms:
1. Used to connect medium pressure tubing with a conical male seat and left-
handed threads to a female port using a gland nut and left-hand threaded
collar (Gland, Collar & Tubing).
2. For many medium pressure male fittings, the geometry of the gland, collar,
and tubing is combined into one component that connects directly to a
medium pressure female port (Single Piece Style).
• With proper care, this connection is suitable for repetitive connection/
disconnection.
• Damage from repeated or improper use can often be repaired using reconing
tools. For details on tubing preparation and repair equipment, contact
Jetstream Sales.
Connection Instructions
1. 3-piece Male Connection Style only — Liberally apply anti-seize to male
tubing threads to prevent thread galling.
2. 3-piece Male Connection Style only — Slide gland nut over tubing and
thread collar (left-hand threaded) onto tubing until it is past the first one or
two full threads of the tubing.
3. Both Styles — Liberally apply anti-seize to male connection threads and
male cone.
4. Both Styles — Install male connection into female port and tighten
according to torque specification in chart above.
