Question by: Marvin A on Jun 12, 2025, 8:31 PM

Got a charge air cooler setup with a sharp angle on the intake side, will a 4 inch 90 degree elbow actually give me enough straight run to clamp down properly?

Six inches of straight leg on that elbow gives you plenty of room to seat a clamp or coupling hardware without fighting it. That straight run is long enough for standard clamping hardware used on large-bore connections, so you should be able to get a solid, secure fit on both ends without any rigging or adapters.

What kinda temps can this hose handle without melting or cracking on me?

Silicone construction gives this elbow fitting good heat resistance, so it's suited for demanding industrial and heavy-duty engine environments where standard rubber might not hold up. It's made for high-temperature air and fluid transfer applications.

got a tight spot on a 4 inch run, is this the kind of elbow that’ll turn it 90 and still give me enough straight to clamp on?

Answer by: Customer Support on Sep 14, 2025, 4:58 PM

For a 4.00 inch inside diameter connection that needs a right angle, this elbow gives you a 90 degree change in direction and includes a 6 inch straight leg so you have some straight run to seat and clamp securely.
