The PARKER 4 TLFA GAUGE is a compression tube Fastseal tubing making gauge designed for preparing and verifying tube ends to Flat-Face and O-Ring Face Seal (ORFS) specifications. Manufactured from steel, this gauge gives technicians and pipefitters a reliable reference tool when forming tube ends to meet sealing surface requirements. It is compatible with Flat-Face, ORFS, and tube end connection configurations. Its compact size makes it easy to carry and use on-site during hydraulic or pneumatic line fabrication work. Trades working with Parker Fastseal fittings will find this gauge an essential part of proper tube end preparation.
This tubing making gauge is intended for use in hydraulic system assembly, pneumatic plumbing, and industrial tube fabrication applications where Flat-Face or ORFS connections are specified. It is specifically noted for use with the Parker 4 TLFA-S fitting. The gauge supports accurate tube end forming to help ensure leak-free assembly at connection points in fluid power systems. Both commercial and industrial installers working with Parker Fastseal compression tube fittings will find this tool applicable to their fabrication process.
Designed for use with the Parker 4 TLFA-S fitting as noted in the product specifications. Suitable for Flat-Face x ORFS x Tube end connection configurations within the Parker Fastseal compression tube fitting system.
This gauge is a tube end preparation and verification tool, not a pressure-bearing fitting. Pipefitters and hydraulic technicians should consult Parker installation instructions for the associated Fastseal fittings before fabricating tube assemblies. Ensure all system pressure is relieved and fluid is isolated before inspecting or replacing any fittings or tube ends in an active hydraulic or pneumatic circuit. Follow applicable industry and facility standards for tube bending, cutting, and end forming.
