Silicone Hose Coupler 89 mm ID

When a custom turbo or supercharger pipework setup needs a straight connection, getting the hose diameter and length right matters as much as the material. This 4-ply silicone coupler is designed for charge piping and compressor inlets, with an 89 mm inside diameter and a 12 in length. It comes with four stainless steel T-bolt clamps, so the package includes the hardware specified for securing the hose. Before choosing it, match those dimensions to your setup rather than relying on the broad vehicle-use description.

Highlights

The coupler has a 5 mm wall and a four-ply silicone construction. The listed temperature range is -140°F to 428°F, and the stated bursting pressure is 2 MPa. These figures may help when comparing hose specifications, but they don’t confirm fitment for a particular vehicle or custom build. The package contains one straight silicone hose and four stainless steel T-bolt clamps, no vehicle-specific application details are provided.

Its straight format is intended for a direct connection, not for routing around a bend. Keep in mind that the 89 mm inside diameter and 12 in length are fixed dimensions, so a hose that looks close may still be unsuitable if your connection points require a different size or shape. The product description calls it leak-free, but a claim like that is not a substitute for matching the parts and installing the connection correctly.

How to use it

This coupler is described for custom turbo and supercharger charge-piping setups, custom compressors, and turbocharged or supercharged vehicle inlets. The listing also mentions boats and other vehicles, but it doesn’t name specific makes, models or engine configurations. Treat it as a component to assess against your own layout, not as a confirmed bolt-on fit for a particular application.

For a practical check, picture the connection between two straight sections of charge piping: measure the relevant outside diameter at the join and compare it with the hose’s 89 mm inside diameter, then make sure the 12 in length suits the available space. The four included T-bolt clamps are part of the package, but the listing doesn’t provide their size range. If your setup needs a curved coupler, a different diameter or confirmed vehicle-specific compatibility, this description doesn’t establish that this part will meet the requirement.

Practical tips

Before ordering, compare the hose dimensions with both connection points and consider whether a straight coupler matches the path your pipework needs to take. Check that the clamping arrangement in your setup can work with the included T-bolt clamps, their detailed measurements aren’t supplied. These simple checks matter more than the broad application list, especially for a custom build where the space around the connection can be limited.

It’s a good choice if you need a straight 89 mm silicone section for a custom charge-piping or compressor-inlet setup and the supplied length suits the layout. It won’t suit you if you need a bend, a different size, or documented fitment for a specific vehicle. Compared with sourcing a shorter or more basic hose section, this package gives you a longer coupler and four clamps, but it still leaves the fitment decision to your measurements.

Buying questions

What comes in the package? One straight silicone hose and four stainless steel T-bolt clamps.

What are the hose dimensions? The listing gives an 89 mm inside diameter, a 12 in length and a 5 mm wall thickness.

Is it confirmed for my vehicle? No specific vehicle fitment is listed. Compare the dimensions with your setup before choosing it.

In your case

Choose this coupler when your measurements call for a straight hose with an 89 mm inside diameter and the 12 in length works for the space available. Its four-ply construction and included clamps are relevant details for a custom piping job, but they don’t make it a universal fit. If the connection needs a bend, a different diameter or vehicle-specific confirmation, look for a part that states those requirements directly.
