How to Measure Threaded Pipe Size

UV-Resistant Polypropylene Pipe Fittings for Chemicals

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

Schedule 80 fittings have thicker, stronger walls than Schedule 40 fittings for heavy duty, industrial chemical processing applications.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Connect the flanged end to another quick-clamp fitting with a clamp and a gasket (all sold separately). Fittings are polypropylene, which resists a wide variety of acids, solvents, and other harsh chemicals. The fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Right-Angle Flow Rectangular Manifolds

Outlets on One Side

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers. They have mounting holes, so you can mount from the top or side.

Polypropylene manifolds have better moisture resistance than other plastic manifolds, so they won’t soften and lose strength in high-humidity applications.

Use a plug (sold separately) to close off any unused inlets and outlets.

Plastic Barbed Hose Fittings for Water

Made of polypropylene, these fittings have good corrosion and abrasion resistance, and are lighter in weight than metal barbed hose fittings. Slide the barbed end into plastic or rubber hose and secure with a clamp.

Fittings with a threaded end are also known as hose nipples.
