FTTP-Series-Parts

Supported Applications

The Omega FTTP Series provides replacement components for PFA compression fittings designed to interface with tubing systems. These parts utilize the Grab-Seal System, which enables positive sealing through a tool-free installation method involving cutting tubing to length and tightening the nut by hand. Documented application areas include biomedical, chemical, petro-chemical, food processing, and semiconductor industries.

Operating Conditions & Performance

The series is constructed with PFA wetted materials and carries RoHS compliance certification. The source documentation does not provide specific pressure ratings, temperature limits (ambient or process), burst pressures, or dimensional tolerances for the fittings. As a catalog of replacement components rather than a technical specification sheet for sensors, performance metrics such as accuracy class, response time, hysteresis, and repeatability are not applicable to this series.

Material Composition

• Wetted Materials: PFA

Configuration Options

The FTTP Series offers a range of individual replacement parts and complete fitting configurations. The available components include Nuts, Grab-Seal Grippers, Grab-Seal Ferrules, Plugs, and Panel Nuts. These items are sized to match specific tube outer diameters (OD) ranging from 1/8 inch to 1 inch.

Replacement Parts

The following components are available as individual SKUs for maintenance or assembly:

• Nut: Model codes FTTP-2N through FTTP-16N (e.g., FTTP-2N, FTTP-4N).
• Grab-Seal Gripper: Model codes FTTP-2G through FTTP-16G.
• Grab-Seal Ferrule: Model codes FTTP-2F through FTTP-16F.
• Plug: Model codes FTTP-2P through FTTP-16P.

Fitting Configurations and Sizes

The series supports various fitting types including Straight Male Adaptors, Union Elbows, Union Reducers, Male Elbows, Union Panel Mounts, Unions, Male Branch Tees, and Male Run Tees. Model numbers follow the pattern FTTP-. Available tube OD sizes include 1/8 inch (2), 1/4 inch (4), 3/8 inch (6), 1/2 inch (8), 3/4 inch (12), and 1 inch (16). Specific configurations link these tube sizes to NPT or NPTF pipe threads, such as FTTP-22 (1/8" Tube OD / 1/8" Pipe Size NPT) up to FTTP-1616 (1" Tube OD / 1" Pipe Size NPT).

Panel Nut Dimensions

Panel nuts are available with specific hex flat dimensions corresponding to tube sizes:

• FTTP-2PN, FTTP-4PN: 3/4 inch Hex Flat (1/8" and 1/4" Tube OD)
• FTTP-6PN: 1 inch Hex Flat (3/8" Tube OD)
• FTTP-8PN: 1 1/4 inch Hex Flat (1/2" Tube OD)
• FTTP-12PN: 1 5/8 inch Hex Flat (3/4" Tube OD)

Key Product Differences

Variations within the FTTP Series are defined by fitting geometry and connection type. The series distinguishes between straight adaptors, elbows, tees (branch vs. run), unions, reducers, plugs, and panel mounts. Thread types vary by model; some fittings specify NPT pipe sizes while others specify NPTF thread standards for male branch or run tees.

Individual replacement components are differentiated solely by the tube OD they service, with no additional functional variations documented beyond size compatibility within the Grab-Seal System architecture.
