Moisture-Resistant Polyethylene (HDPE) Balls

Color: Semi-Clear White
Temperature Range: Not Rated
Tensile Strength: 3,920-4,200 psi (Poor)
Impact Strength: 1.1-1.94 ft.-lbs./in. (Poor)
Hardness: Rockwell R40-R80 (Medium)
For Use Outdoors: No

Often used in check valves, relief valves, and float valves, these balls won’t swell when exposed to water. HDPE offers good chemical resistance.

Polyethylene Unthreaded Spacers

Almost nonabsorbent, these unthreaded LDPE and HDPE spacers won't swell when exposed to water.

HDPE spacers are harder, denser, and more chemical resistant than LDPE spacers.
