Specifications
| Body Type | Sandwich |
|---|---|
| Interface | ISO 07 |
| Body Features | Cushion lock |
| Stack Height | 4.33 in. (110 mm) |
| Seal Plate Included (see notes) | Yes |

Stack height value in technical data table includes seal retainer plate. Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.
How to read BK8
Sun part numbers are the model followed by one code per option. Hyphens, slashes and spaces are only dividers, so BK8, BK8/10, BK8/11, BK8/15, BK8/16, BK8/V, BK8/S, BK8/S3, BK8/S4, BK8/S5, BK8/Y, BK8/Y3, BK8/Y4, BK8/Y5 are the same part.
| Model | BK8 — Sun Hydraulics ISO 07: Cushion lock Sandwich manifold |
|---|---|
| Modifier | Add the modifier after the model, e.g. BK8/10 = black anodized aluminium. No modifier = standard material. |
