5323-70 Meets Your Needs

1. Outstanding Resistance to

Compression Set

Parco seals made from peroxide-cured 5323-70

have excellent resistance to compression set. After

testing 5323-70 for 22 hours at 257°F, it had a

compression set of only 13 percent. At 13 percent,

5323-70 significantly outperforms similar sulfur

cured EPDM compounds. 5323-70’s excellent

compression set allows it to better maintain its

elastomeric properties and original thickness,

preserving seal integrity.

2. Excellent Resistance to

Chloraminated Water

Parco’s peroxide-cured 5323-70 compound has

superior resistance to volume swell in

chloraminated water applications. After testing for

70 hours at 212°F in chloraminated water, 5323-70

seals experienced volume swell of one percent.

That low volume swell makes seals made from

peroxide-cured 5323-70 substantially better than

similar sulfur-cured compounds. Parco recommends

its 5323-70 compound for chloraminated or

chlorinated applications such as faucets, hose bibs,

and other residential plumbing fixtures.
