The STAUFF Cover Plate DPL is an essential technical component for the secure and durable installation of clamp bodies belonging to the Light Series with twin-pipe configuration, also known as Twin Design. Within complex fluid, pneumatic and hydraulic systems, this element acts as a structural upper closing plate, ensuring optimum and even distribution of the clamping force on pipes, flexible hoses or rigid conduits.<\/p>\n

Construction Materials and Technical Specifications<\/h3>\n

The standard plate model is identified by the suffix and material code W3, which indicates that the component is manufactured entirely from carbon steel and subsequently treated with a zinc\/nickel-plated surface finish. This specific technical coating provides excellent corrosion resistance, making the component particularly suitable for complex industrial environments subject to wear. The manufacturer specifies that variants with alternative materials and surface finishes are available upon request to meet particular operating requirements. A key technical parameter for correct installation concerns the tightening torque: the maximum recommended force applied to the fastening bolts must not exceed 2.5 N-m (corresponding to 1.85 ft-lb).<\/p>\n

Compatibility with Clamp Bodies (Twin Design)<\/h3>\n

The DPL Cover Plate acts as a complementary closing element for Light Series fastening clamps in the Twin Design configuration. More specifically, it is fully compatible with Type LNGF models, designed to accommodate parallel pipes with identical outside diameters, as well as Type LNUF models, which are specifically intended for combinations of pipes with different outside diameters. These clamp bodies, onto which the plate is mounted and tightened, are typically manufactured from standard plastic materials such as Polypropylene (identified by material code PP, green) or Polyamide (identified by material code PA, black).<\/p>\n

Applications and Fields of Use<\/h3>\n

Thanks to its considerable structural strength and reliability, the technical combination of the clamp bodies and the corresponding DPL upper plate is widely used across many different industrial sectors. The main and most recommended applications include pneumatic systems, technical instrumentation, automotive technology and the machine tool industry. In addition, the fastening system provides a highly standardised and efficient solution for industrial lubrication networks and general mechanical engineering.<\/p>\n

Physical Dimensions and STAUFF Groups<\/h3>\n

The standard DPL plate range is engineered and structured in four different sizes, rigorously classified according to progressive STAUFF Groups 1 to 4. The physical dimensions of the component vary proportionally according to the specific group selected for installation: the overall length, identified as dimension L4, ranges from a minimum of 29.5 mm for Group 1 components up to 63.5 mm for Group 4 components. At the same time, the plate width, indicated as B2, varies within a very narrow range from 15.5 mm to 16 mm. A technical detail that supports mounting standardisation is the diameter of the holes provided for the fastening bolts (dimension \u00d8 D4), which remains constant throughout the entire range at 6.8 mm.<\/p>\n
