Goulds Mechanical Seal — 12 mm (10K168 / 10K172)

Direct-fit 12 mm mechanical seal for Goulds vertical multistage pumps. Built for reliable sealing in high-duty service with hard faces and chemical-resistant elastomers.

Fits pump models: Goulds 1SV, 2SV, 3SV, 5SV

Standard material (for this stock): Faces: Silicon Carbide / Silicon Carbide (SiC/SiC); Elastomers: Viton (SIC/SIC/VIT)

Note: 10K168 and 10K172 share the same design and fit. Because we supply the upgraded SiC/SiC/Viton build as standard, our 10K168 meets the 10K172 material specification—the two references are interchangeable in our catalog.
