New Original FESTO 8069217 NPFC‑D‑2G34‑M Double‑Threaded Pneumatic Fitting

Product Overview

The FESTO NPFC‑D‑2G34‑M, part number 8069217, is a brand‑new original double‑nipple straight pneumatic fitting belonging to the NPFC threaded fitting series. This component features male‑to‑male G3/4 parallel thread connections on both ends, designed to join two pneumatic ports with matching G3/4 male‑female interfaces. Manufactured from nickel‑plated brass, it is widely used for pipeline interconnection of pneumatic valves, air preparation units, cylinders, pressure regulators and vacuum circuits in factory automation equipment. Marked as “New Original”, it represents genuine factory‑produced fittings with complete surface treatment and full‑factory inspection, free of refurbished or second‑hand parts. It supports both compressed‑air and vacuum working conditions for general industrial pneumatic systemsFesto.

Main Functions

1. Straight‑through pipeline connection: Links two pneumatic components with G3/4 female ports via double male‑thread ends to build continuous air flow channels.
2. Vacuum‑compatible connection: Works reliably within vacuum circuits down to ‑0.95 bar for negative‑pressure automation applications.
3. Pneumatic circuit extension: Realizes inline pipeline extension when extra connecting length is required between pneumatic devices.
4. Standard‑thread transition: Adapts matching G‑thread interfaces for valves, service units and actuators without thread‑size reduction.
5. Tool‑assisted assembly: Hexagonal middle body allows tightening with standard open‑end or box spanners for stable installation torque control.
6. PWIS‑compliant connection: Suitable for painting‑process automation systems without risk of paint‑wetting defects.
7. Multi‑medium adaptability: Primarily for filtered compressed air; compatible with selected non‑aggressive gases upon requirement.

Technical Characteristics

• Body constructed from nickel‑plated brass, providing good mechanical strength and CRC 1 low‑corrosion‑stress performance for indoor industrial environmentssp-sparepa….
• Double‑ended male G‑parallel thread design, straight‑through flow passage with no internal flow obstruction.
• Complies with VDMA 24364‑B1/B2‑L LABS‑PWIS standard for painting‑industry equipment; RoHS‑compliant raw materialsFesto.
• Wide operating pressure range covering vacuum up to high positive pressure, suitable for heavy‑duty pneumatic circuits.
• Broad ambient‑temperature tolerance for high‑temperature workshop working conditions.
• No built‑in sealing gasket; PTFE thread‑sealing tape is recommended for reliable leak‑proof assembly.
• Standard industrial hexagon profile for convenient mounting and dismounting with common hand tools.

Product Dimensions

All dimension values are given in millimetres.

1. Overall total length: 44 mm
2. Hexagon across‑flat width: 32 mm
3. Thread length per male‑thread end: 14 mm
