Instrumentation Tube Fittings
Tube fittings are critical components in fluid conveying systems because they secure connections between tubes and ports. All connections are potential leak points in fluid systems. To help assure a leak free solution for your specific application, it is important to work with a knowledgeable supplier that understands fittings, assemblies and can offer multiple designs.
Omni Services stocks a wide variety of tube fittings, including single ferrule, double ferrule, o-ring seal face, flanged, flared, compression, bit style, and push to connect tube fittings, all of which are readily accessible at any of our retail locations.
Whether you just want to understand the differences between pipe fittings and compression fittings, or you are searching for the right fitting for your application, Omni Services Instrumentation and Process Division is dedicated to helping you source the right leak-free connections.
Omni Services can also supply stainless steel tubing and other tube alloys to move fluid and gas through your process system. Omni Services works with all situations and has the fittings you need to create your successful fluid conveyance solution. Connect with Omni Services today.

Instrumentation Products
Omni Services is a stocking distributor of many different tube fittings for instrumentation, process and purity applications, as well as supplying tubing, valves, controls, and sensors. Omni has extensive experience with the components that make up complex fluid transfer systems, and because of this Omni is often called upon to help engineer the correct components for individual customer applications.
Omni is a unique partner in that we also have a formed tube division that bends hard wall tubing for production builds. Tube fittings connect these formed tubes, hoses and other components to complete your fluid transfer system. The key to tube fitting selection, is ease of assembly, reliability (leak proof), re-makeability, and competitive pricing.
Tube fittings are available in a variety of materials based on your media compatibility: 316 SS, Alloy 400, C-276, brass, PTFE, Nylon.

SSP Duolok® Tube Fittings
are engineered two ferrule Swage design tube fittings which provide efficient, reliable, remakeable, leak-proof connections in instrumentation and process systems. Warranted interchangeable and intermixable with industry standard two ferrule designs.

SSP Unilok® Tube Fittings
offer engineered single ferrule Swage design tube fittings to provide an efficient, reliable, remakeable, leak-proof connection in instrumentation and process systems. Warranted interchangeable and intermixable with industry standard single ferrule designs.

SSP Griplok® Tube Fittings
Offer another two ferrule Swage design tube fitting, to which also provides efficient, reliable, remakeable, leak-proof connections in instrumentation and process systems

Face Seal Fittings
Face Seal Fittings Use FR or FO series O-ring seal face fittings for high purity applications. Face seal O-rings provide high performance, high purity tube fitting sealing. Either design helps eliminate the possibility of environmental contamination or bacteria traps within the media stream.
The “FR” and “FO” are slightly different designs, using either elastomeric or metal O-rings to provide the pressure and hi-vacuum seals.

Soft Seal O-ring Face Seal Tube Fittings
Soft-Seal O-ring Face Seal Tube Fittings offer zero clearance tube connections. The Soft-Seal design offers unlimited re-makeability and is forgiving of tube system misalignment and high vibration.
The replaceable elastomeric seal provides superior sealing of fluids and gases at high pressures and vacuum. The high durometer O-ring is held in a precision-machined groove in the fitting body. Available in a myriad of patterns and sizes.
Soft Seal, SAE O-ring Face Seal Fittings

37° Flared Tube Fittings
37° Flared Tube Fittings are the original “tube fitting” and still the most widely used design. The SAE flared tube fittings rely on metal-to-metal contact between the finished surface of the fitting nose and the inside diameter of the flared tubing to make a seal.
SSP takes great care in the manufacturing process to produce a flared nose surface that far exceeds industry standard specifications. This high finish reduces the likelihood of leakage due to irregularities in the flared tubing.

Ultra Flare Fittings
Ultra Flare Fittings In addition to the proven 37° design, The Ultra-flare fitting uses a Teflon seal placed into a machined trepan, to assure seal proper alignment.
This seal allows for greater pressure capability, greater remakeability and helps accommodate for tubing misalignment, and sealing surface imperfections.

General Purpose Push to Connect Tube Fittings
General Purpose Push to Connect Tube Fittings are ideal for pneumatic installations. Fittings are available in composite polymers, brass, nickel plated brass, and SS. This most user-friendly tube fitting merely requires a simple push of the tubing into the body for a leak-proof connection.
Fittings are capable of handling pressures to just over 200 PSI and industrial vacuum ratings (28” Hg). These push to connect tube fittings are designed primarily for polymeric tubing.
