Poly Nipples - Polypropylene Pipe Nipples

Polypropylene nipples connect two female pipe threads with a light, completely corrosion-proof body. They are the standard choice for chemical tanks, soft wash mix stations, bleach and detergent lines, and anywhere metal fittings would corrode or add weight.

Male pipe thread (MPT) on both ends, matched size. Hand tight plus a turn - do not over-torque plastic fittings.

• Polypropylene - will not corrode with bleach, acids or detergents
• Male pipe thread both ends, matched sizes
• Sizes 1/4", 3/8", 1/2", 3/4" and 1"
• Low pressure and chemical transfer use - not for high pressure discharge
• Use PTFE tape, not pipe dope, on plastic threads

For pressurized lines, see our brass, steel and 304 stainless hex nipples.
