How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

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.

Stainless Steel High-Pressure Barbed Tube Fittings for Air and Water
- Temperature Range: See table
- Tubing: Use with firm (Durometer 75A-95A) EVA plastic, polyethylene plastic, polypropylene plastic or PVC plastic
Fittings withstand pressures up to 250 psi. They are 303 stainless steel for very good corrosion resistance.

Brass Compression Tube Fittings for Air and Water
- For Use With: Air, Lubricated Air, Water
- Temperature Range: See table
- Tubing: Use with firm or hard (Durometer 1A-95A or Rockwell 15T 1-15T 60) nylon plastic, polyethylene plastic, polypropylene plastic or polyurethane rubber
- Specifications Met: SAE J512, except metric sizes
A single sleeve (ferrule) compresses the tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings. They are brass for good corrosion resistance.
- Temperature Range:
Inch: -65° to 250° F
Metric: -40° to 250° F - Tubing:
Tube supports with 135 psi @ 75° F or 165 psi @ 75° F max. pressures: Use with firm or soft polyethylene plastic or PVC plastic
Tube supports with all other max. pressures: Use with firm or soft (Durometer 1A-95A) polyethylene plastic or polypropylene plastic
- For Use With:
Short nuts: Air, Water, Lubricated Air

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.
- Maximum Pressure: 150 psi @ 72° F
- Temperature Range: 10° to 150° F
- Attachment Type: Use Worm-Drive Clamps or Bolt Clamps
