New High Pressure ISRI NTS2 Seat Control Valve Connector Tube for Heavy Duty Truck Seats 947519-19/00E
The New High Pressure ISRI NTS2 Seat Control Valve Connector Tube—part number 947519-19/00E—is a specialized fluid transfer component engineered exclusively for ISRI NTS2 heavy-duty truck seat control valves. Built to withstand the high-pressure demands of pneumatic/hydraulic seat adjustment systems (up to 16 bar), this brand-new connector tube resolves critical failures of standard tubes, including burst under pressure, leaky joints, and corrosion-induced blockages—ensuring uninterrupted fluid flow to the seat control valve for reliable adjustment performance.
Crafted for extreme pressure resistance and durability, the tube features a triple-layer construction: an inner core of seamless stainless steel 316L (known for high tensile strength and chemical resistance), a middle layer of reinforced braided stainless steel (boosting burst pressure tolerance by 80% compared to single-wall tubes), and an outer jacket of abrasion-resistant PVC. This design not only handles the peak pressures of ISRI NTS2’s hydraulic/pneumatic systems but also resists damage from cab debris, vibration, and exposure to diesel, hydraulic oil, and road salts—outperforming rubber or low-grade steel tubes that degrade within months.
At both ends, precision-machined brass compression fittings (with 1/4" BSPP threads) ensure a leak-tight seal with the ISRI NTS2 control valve and seat fluid lines. The fittings incorporate dual O-rings made from FKM (Viton) rubber, which maintain elasticity and seal integrity across a temperature range of -40°C to 150°C—eliminating the “cold leak” or “heat hardening” issues common with nitrile seals. A built-in tube support sleeve prevents kinking at the fitting junction, a major cause of restricted flow in generic connector tubes.
Engineered as a direct OEM replacement for ISRI NTS2 seat systems, the tube adheres strictly to the length (pre-cut to 350mm) and dimensional specifications of part number 947519-19/00E. It fits seamlessly into the existing fluid routing of heavy-duty truck seats (compatible with ISRI NTS2-equipped MAN, Scania, and Mercedes-Benz trucks), requiring no modifications to the valve or seat plumbing. Installation is tool-efficient: the compression fittings tighten with a standard wrench, creating a permanent seal in under 5 minutes—reducing maintenance time for fleet teams.
Each tube is supplied in 100% new condition, with no used or refurbished components, and undergoes rigorous high-pressure testing: a 24-hour static pressure test at 24 bar (150% of rated pressure) and a dynamic pressure cycle test (10,000 cycles from 0 to 16 bar) to ensure burst resistance. It also complies with SAE J1405 (automotive high-pressure fluid tube standards) and ISO 4413 (hydraulic fluid power specifications), meeting global heavy-duty truck industry requirements.
For truck drivers, the reliable fluid flow ensures consistent seat adjustments (height, recline, suspension) even under high-pressure system loads, eliminating the “jerky” or unresponsive adjustments caused by faulty tubes. For fleet managers, the tube’s durability cuts replacement frequency by 3–4 times compared to generic alternatives, while its OEM compatibility eliminates fitment errors. The part number 947519-19/00E also simplifies inventory management, aligning with ISRI’s official parts catalogs.
In summary, the New High Pressure ISRI NTS2 Seat Control Valve Connector Tube 947519-19/00E is a mission-critical component for heavy-duty truck seats. By merging triple-layer high-pressure construction, leak-tight seals, and ISRI-perfect fitment, it delivers the reliability and performance that drivers and fleet operators depend on in demanding trucking environments.
