The DDS is offered in either PEEK or titanium with a cracking pressure of 5 psi. A vacuum and fill attachment is available.

The Single Dual Seal (SDS) has an adjustable cracking pressure range of 5-15 and 15-25 psi. Materials include aluminum, stainless steel, or titanium. A vacuum attachment is available.
