Seal House stocks over 17,000 standard product lines, but there are times when a Custom Seal is the best option.
Seal House are Custom Sealing solutions specialists. We offer a wide variety of Custom Seal options to suit almost any application.
We use state-of-the-art CNC technology and superior, quality seal materials. We have an extensive knowledge base, which has been built up over the years, initially while trading as Sealjet, a name synonymous in the New Zealand market place with precision and quality.
We can optimise seal life and performance by expertly custom-manufacturing your seals to suit a particular environment. Our Custom Seals can meet your sealing needs in the most demanding of applications, including:

  • Food grade,
  • Low friction,
  • Hydrolysis resistant and
  • Aggressive chemical environments

Seal House has 3 dedicated seal machines capable of machining seals up to 550mm (OD) in diameter. We can supply a single seal, for a one-off application, or a run of 1000.

We can either adapt an existing standard profile or custom manufacture to suit.
