It uses a 24-degree flare angle bite mechanism to grip tubing without flaring, creating a secure, leak-resistant connection. Rated to 5,000 psi maximum working pressure, this fitting is built from steel for durability in demanding service environments. With an overall length of 2.18 inches and a 1\/4 inch tube OD port paired with a 1\/4 inch NPTF male thread, it is sized for compact inline branching applications. Hydraulic technicians and instrumentation fitters install this fitting in fluid power, process control, and industrial pneumatic lines.\u003c\/p\u003e\n\u003cp\u003eThis tee fitting is used where a branch takeoff is needed along the run of a tubing line without interrupting flow to the primary downstream connection. It is suited for residential and commercial hydraulic systems, machine tool circuits, and instrumentation panels where a flareless connection is preferred over flared or compression alternatives. The NPTF thread seals on the threads themselves, making it appropriate for pressure lines where thread sealant or tape is applied per system requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlareless bite-type design eliminates the need for pre-flaring tubing before installation\u003c\/li\u003e\n  \u003cli\u003e5,000 psi maximum working pressure rating for high-pressure hydraulic and instrumentation service\u003c\/li\u003e\n  \u003cli\u003e24-degree flare angle for positive tube grip and leak-resistant sealing\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPTF male thread provides pressure-tight thread sealing\u003c\/li\u003e\n  \u003cli\u003eSteel construction for strength and resistance in industrial environments\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 2.18 inches supports tight-space installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for high-pressure hydraulic, pneumatic, and instrumentation tubing systems using 1\/4 inch OD tubing with 1\/4 inch NPTF ported connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified hydraulic or instrumentation technicians. Depressurize and isolate the system completely before removing or installing any fittings. Apply thread sealant or PTFE tape to the NPTF male threads in accordance with the system fluid and pressure requirements. Tighten fittings using appropriately sized wrenches — do not use pipe wrenches on tube bite components, as jaw damage can compromise the bite ring seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Male Run Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Style\u003c\/strong\u003e: Flareless Bite-Type\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlare Angle\u003c\/strong\u003e: 24 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 5,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.18 inches\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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: 4-4-4 RBU-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538521915698,"sku":"4-4-4 RBU-S","price":49.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0f7135822f0005c47a8d4dbdb3a8d29.jpg?v=1785824931","url":"https:\/\/voomisupply.com\/products\/parker-4-4-4-rbu-s-male-run-tee-1-4-inch-nptf-steel-5000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
