SpiroFlex 80 elbow (PP) 87° for base (S) plumbing fitting SX-PPJ80K87PP

SpiroFlex 80 elbow (PP) 87° for base (S) is a polypropylene plumbing fitting intended for use with 80 mm duct or pipe systems. The fitting provides an approximate 87-degree change of direction and is manufactured from chemical-resistant PP, making it suitable for ventilation, drainage and waste systems where a near-right-angle bend is required. It is designed for connection to a base (S) component and for reliable routing of air or fluids in systems that use 80 mm diameter ducts.

Advantages

The polypropylene construction ensures corrosion and chemical resistance while remaining lightweight. The 87° angle offers a near-right-angle turn that minimizes space requirements compared with larger-radius fittings. The product is engineered for consistent dimensional accuracy to enable secure mechanical connections to compatible 80 mm duct components and to reduce the need for additional sealing in standard installations.

Suitable for

• 80 mm ventilation duct systems requiring an angled turn
• Drainage and waste piping with chemical exposure
• Retrofit or new installations where a base (S) connection is specified
• Indoor HVAC routing where compact directional changes are needed

Key specifications

• Material: polypropylene (PP)
• Diameter compatibility: 80 mm ducts/pipes
• Angle: 87° directional change
• Connection type: intended for base (S) component connection
• Typical applications: ventilation, drainage, waste systems

How to use

Confirm compatibility of the 80 mm duct system and ensure the base (S) component matches the fitting profile. Clean mating surfaces to remove debris and install the elbow by aligning it with the duct ends and pushing or securing according to the systems connection method. For systems that require mechanical fixing, use the appropriate clamps or fasteners; for sealed systems, apply compatible sealant following manufacturer guidance. Verify alignment and test the system for leaks or airflow restrictions after installation.

Usage recommendations

Use the fitting within the recommended temperature and chemical exposure ranges for polypropylene. Avoid excessive mechanical stress at the joint and support adjacent duct runs to prevent sagging. Periodically inspect connections for wear, deformation or seal degradation, especially in systems exposed to aggressive chemicals or temperature cycling.
