Housing, Shaft &
Seal Material Options

Temperature, media, speed, pressure and environment all have a big impact on the performance of our products.

If your application requirements fall outside our standard product's specifications we'll review all possibilities, including the use of different material options.

Configuration Options

We understand that not all of our standard products will integrate directly into your equipment. We've designed them to be as universal as possible but sometimes that just isn't enough. Our engineering team will work fast at finding a solution that better suits your mounting and connection needs.

Housing & Shaft
Dimensional Changes

Applications with very tight or unique size constraints are often limited on the selection of rotary union options available - therefore, require some form of modification. Regardless of the scale of complexity of a change, DSTI will work side-by-side with your team to deliver a product that fits your exact spacial requirements.
