OG™ FlushFor True Premium Gas Tight Metal Sealing

Precision is dedicated to the development of new premium and semi premium connections to meet the challenges of horizontal well completions. We provide classic and innovative ways to keep your tubing and casing connected tighter, safer, and stronger. This allows you to maintain schedules, drastically reduce safety concerns and save on operational costs. Whether you are looking for API couplings, semi-premium or premium connections, we’ve got you covered.

The OG™ FLUSHWas designed to provide maximum gastight sealing and strength.

Designed for plain end pipe with externally and internally flush profiles. The design is swaged to correct the pipe geometry and ensure strength.

A true double shoulder design for torque capacity. Reduced sensitivity to over-torque.

Multiple Sealing Mechanisms– Radial Metal pin nose seal, OD metal radial sea and OD reverse angle torque energized seal.

OG™ FLUSH Inner SealBall on Cone design for proven sealing in high bends.

Large radius pin nose on a low angle box taper to maximize seal contact area.

Swaged pin nose to guarantee thickness and sealing.

OG™ FLUSH Outer SealReverse Angle torque shoulder seal.

Radial Seal Bump for collapse resistance

Reverse angle to create a compressed seal trap against the radial seal bump.

The OG™ FLUSHTensile and Compressive strength are designed to 60% to 70% of pipe body ratings depending on wall thickness. Compression may be lower for 3.5’” Pipe and smaller due to column buckling. 60% is still good for bending calcs.

Collapse resistance equal to API collapse pressures or rated pipe collapse for proprietary grades.

Internal Pressure rated to 100% of pipe body internal yield pressure.

Boxes and Pins are threaded with tight tolerances and 100% element inspection.

Pins are swaged, stress relieved and threaded to ensure maximum strength.

Patented Leak Tight Thread FormReduces thread gap and Splits the thread compound into 2 flow path regions.

Non contacting separation at the apex to restrict flow and aid sealing.

Patented Leak Tight Thread Form

Uses taller Square Stepped Threads. Flat Crests and Roots.

Negative load flanks for bending and jumpout resistance.

Tight thread spacing for sealing.

Square threads for deep stabbing and easy make up .

Tight Contact: Contacts on 3 of the 4 possible mating surfaces.

Tight to restrict movement in a bend or compression.

Thread Assembly

Thin Wall: 8 pitch VS 10.Medium Wall: 6 pitch VS 8.Thick Wall: 5 pitch VS 4.

Fewer threads per inch for a faster stab and makeup.

They stab deep just like tapered threads for stable make ups.

Square stepped threads assemble quickly. They are resistant to bind up.
