Is the VSTI-ME Stainless Steel Plug compatible with hydraulic fluids and pressures up to its 4:1 safety factor rating?

Yes. The VSTI-ME Stainless Steel Plug is designed for hydraulic and pneumatic service and, with its elastomer rectangular-cross-section gasket and robust construction, is compatible with hydraulic fluids and pressures within its specified 4:1 safety factor. Its high-quality carbon-steel body with corrosion-resistant galvanization and DIN 3852 type E external thread provide secure, leak-free sealing under demanding conditions, while the 4:1 safety factor ensures reliable operational margin for typical hydraulic systems. Ensure the specific hydraulic fluid is compatible with the plug’s elastomer gasket and verify system pressure does not exceed the plug’s rated working pressure (i.e., ultimate burst pressure divided by 4).

Does the VSTI-ME Stainless Steel Plug require specific torque values when tightened with a hex key to maintain its 4:1 safety factor?

No. The product description for the VSTI-ME Stainless Steel Plug does not specify any required torque values for tightening with a hex key to maintain its 4:1 safety factor. It states a 4:1 safety factor and describes materials, thread standard (DIN 3852 type E), and the elastomer rectangular gasket, but gives no torque or installation-tightening data. For correct assembly and to ensure the stated safety factor in your application, follow manufacturer torque specifications (if available), industry best practices, or consult the supplier/engineering documentation to obtain the recommended hex-key torque.
