Sling Seal Plastic Pipe Seal

The patented design maximizes sealing forces while optimizing pipe jointing forces. This design has a flexible, internal stiffening member, which is more resistant to
dislodging than other sealing systems, as well as features which make it more resilient when separating jointed pipes.

The SLING™ Seal plastic pipe seal was developed using extensive non-linear Finite Element Analysis (FEA). This allowed the seal to be optimized for the best all-around performance prior to
ever producing a single sample. The plastic pipe seal has been tested repeatedly to ensure it meets or exceeds ASTM D3139, AWWA C909, and FM1612.

The SLING™ Seal uses only the highest performing materials. Press-Seal Corporation developed an all new SBR compound to exceed all material requirements as set forth by ASTM F477 HH, while still adhering to NSF 61 and UL 157 to allow use in potable water systems.

The SLING Seal is designed to meet or exceed the highest standards in the industry. These standards include::

• ASTM F477 HH
• ASTM D3139
• AWWA C909
• FM 1612
• UL 157
• NSF/ANSI 61
