It connects a 3\/8-18 female thread to a 3\/8-18 male thread using the NPTF (National Pipe Taper Fuel) thread form, which creates a pressure-tight mechanical seal without requiring a sealant compound. Rated to 6000 psi, this expander is suited for demanding fluid power and instrumentation applications where leak-free connections are critical. Typical installers include hydraulic system technicians, pipefitters, and industrial maintenance mechanics working on high-pressure plumbing assemblies.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in industrial piping systems where a same-size NPTF expander configuration is needed to transition between connection points in tight plumbing layouts. It performs in hydraulic power units, pneumatic systems, and fluid transfer lines operating at or below its rated pressure. The NPTF thread classification ensures compatibility with other NPTF-threaded components throughout the assembly, making it a reliable choice for both new installations and field repairs on industrial equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated to 6000 psi for demanding high-pressure hydraulic and fluid power service\u003c\/li\u003e\n  \u003cli\u003eNPTF thread form creates a dry-seal mechanical connection without sealant dependency\u003c\/li\u003e\n  \u003cli\u003e3\/8-18 male and 3\/8-18 female threads on a single expander body\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides strength and durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003eCompact expander design suits tight plumbing configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install fitting for industrial piping systems using 3\/8-18 NPTF threaded components rated for high-pressure service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter or hydraulic technician. Depressurize and isolate the system completely before removing or installing any fittings. NPTF threads are designed to seal on the thread form itself; inspect threads for damage before assembly and apply thread sealant only if required by the system specification. Follow applicable industry piping codes and the equipment manufacturer's torque and assembly guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Expander\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFemale Thread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Classification\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 6000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.183 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3\/8 FG-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542210183474,"sku":"3\/8 FG-S","price":23.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/856898af2d81da7c08c9f76faf374f80.jpg?v=1785895196","url":"https:\/\/voomisupply.com\/products\/parker-3-8-fg-s-pipe-expander-3-8-18-nptf-steel-6000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
