Product Description

The Wieländer+Schill Type B Mouthpiece (SKU: 703131) is a precision-engineered consumable component designed specifically for professional automotive structural riveting. Engineered to accommodate blind rivets with a diameter ranging from 5.1 mm to 5.5 mm, this specialized mouthpiece is an essential insert for the Wieländer+Schill BR 50 Blind Rivet Adapter.

In modern collision repair facilities across Canada, working with advanced mixed materials requires highly specific fastening hardware. The "Type B" designation indicates that this mouthpiece features a specially machined concave head profile. This geometry makes it the ideal fit for properly seating RIBE blind rivets and other specialized structural fasteners commonly utilized by European OEMs. By integrating seamlessly into the XPress 800 and XSeries modular ecosystems, this mouthpiece ensures technicians can execute flawless, factory-grade blind rivets without risking damage to the rivet mandrel or the surrounding vehicle panel.

Key Features

• Type B Concave Profile: Features a specifically machined concave head designed to perfectly cup and seat specialized automotive fasteners, such as RIBE structural blind rivets.
• 5.1–5.5 mm Capacity: Sized to precisely handle mid-to-large structural blind rivets with shaft diameters falling between 5.1 mm and 5.5 mm.
• BR 50 Integration: Directly compatible with the Wieländer+Schill BR 50 Blind Rivet Adapter, allowing for quick, thread-in tool changeovers during complex structural repairs.
• XPress Ecosystem Compatible: Fits seamlessly into the modular XSeries platform, expanding your shop's capability without the need for standalone riveting guns.
• High-Durability Steel: Forged from high-grade hardened materials to withstand the immense 50 kN pulling force generated by the BR 50 hydraulic adapter without deforming.

Ideal For

• Collision Repair Facilities: Executing OEM-approved structural blind riveting on advanced aluminum and high-strength steel vehicle architectures.
• European Auto Specialists: Safely setting specialized RIBE blind rivets that are common in advanced European body panel and structural assemblies.
• Modular Tool Optimization: Expanding the functional size range of an existing Wieländer+Schill XPress 800 riveting station efficiently.

Common Questions

Q: What is the exact difference between a Type A and Type B mouthpiece?

A: The designation refers entirely to the shape of the mouthpiece head. Type A mouthpieces feature a standard flat head profile, while Type B mouthpieces (like this one) feature a concave head. The concave shape is required to properly seat certain types of automotive fasteners, ensuring the tool does not slip off the rivet flange during the high-pressure pull cycle.

Q: Does this mouthpiece attach directly to the XPress 800 main cylinder?

A: No, it does not thread directly into the main gun. This mouthpiece is designed to thread into the front face of the BR 50 Blind Rivet Adapter, which is then driven by the XPress 800 or XPress 1000 main pneumatic-hydraulic cylinder.

Q: Is this compatible with the smaller BR 20 adapter?

A: No, pulling structural rivets of this size (5.1–5.5 mm) requires the higher 50 kN pulling force and larger physical housing of the BR 50 adapter. The smaller BR 20 adapter is specifically reserved for smaller diameter rivets up to 4.2 mm.
