Fuseal Fast-Lock 1/4 bend 91.2° short sweep

  Datasheet (PDF)

The Georg Fischer Fuseal Fast-Lock 91.2 degrees short sweep 1/4 bend is a flame-retardant polypropylene fitting engineered for corrosive chemical waste drainage. Designed for laboratory, industrial, and institutional DWV systems, this mechanical joint fitting provides directional flow routing with a built-in pitch. It delivers exceptional chemical resistance, withstands working pressures up to 35 psi, and enables rapid mechanical assembly without curing delays.

Technical specifications

The fitting is rated for pressure performance up to 35 psi, making it fully compatible with gravity flow, intermittent vacuum, and pumped laboratory drainage. It accommodates continuous operating temperatures up to 180 degrees Fahrenheit (82 degrees Celsius) and intermittent temperature spikes up to 212 degrees Fahrenheit (100 degrees Celsius).

• System design: Fuseal Fast-Lock mechanical joint fitting with socket by socket ends
• Deflection angle: 91.2 degrees short sweep design to maintain required drainage slope
• Operating pressure: Rated for internal pressures up to 35 psi
• Thermal envelope: Continuous duty up to 180 degrees Fahrenheit (82 degrees Celsius); intermittent up to 212 degrees Fahrenheit (100 degrees Celsius)
• Chemical compatibility: Resistant to corrosive mixtures of mineral acids, alkalis, alcohols, salt solutions, and solvents
• Environmental stability: Heat-stabilized composition with UV-protective pigmentation for above-ground durability

Applications

This short sweep quarter bend is intended for acid waste, drainage, waste, and vent (DWV) piping networks subjected to corrosive chemical discharge. It serves as a dependable upgrade over metallic piping systems vulnerable to electrolytic failure and corrosion.

Typical installations include life science facilities, university and hospital testing laboratories, industrial chemical processing plants, food and beverage processing facilities, and marine drainage installations where hot reagents and mixed chemical effluents are routinely conveyed.

Installation and jointing

The Fast-Lock mechanical joint design enables fast and straightforward dry assembly without chemical cements, applicators, or solvent fumes. The joint utilizes a compact mechanical collar and gasket assembly that is immediately ready for pressure testing and active service upon tightening.

Contractors only require a standard 8 mm or 10 mm socket driver or cordless tool to secure the joint, completely eliminating the need for pipe grooving equipment. Furthermore, the fitting offers complete modularity, featuring interchangeable collar architecture that permits direct field transitions between Fast-Lock mechanical joints and Fuseal electrofusion collars.
