About this range

01What is the difference between braided-hose and spiral-hose fittings?

The tail. Spiral hose has four or six wire layers and a thicker wall, so its fittings use a heavier body and usually a skived ferrule that grips the wire directly. The port end can be identical; the hose end is not interchangeable.

02Skive or no-skive?

Whichever the hose and fitting series are designed for. Skive ferrules need the outer cover — and sometimes the inner tube — removed so the ferrule grips the wire; no-skive ferrules crimp over the cover. Use the ferrule specified for the construction; the two are designed together.

03How do I measure a hose fitting thread?

Measure across the crests of a male thread (or inside a female), measure the pitch — threads per inch, or millimetres between crests — and look at the seat: a 37° flare, a 24° or 60° cone, or a flat face with an O-ring. Diameter, pitch and seat together identify the family. Send them with a photo and we will confirm.

04Should I choose a swivel or a rigid hose fitting?

Use a swivel female wherever you can: its nut turns independently, so the joint is made up without twisting the hose. A rigid male end can only be screwed in by turning the whole assembly, so it is normally fitted first, or mated to a swivel female at the other side. A hose installed with twist in it loses a large part of its life, because the wire reinforcement is loaded unevenly. If both ends must be rigid, add a swivel adapter at one port.

05How do I measure the length of a hose assembly for a replacement?

Measure overall length from the end of one fitting to the end of the other: to the sealing face on straight ends, and to the centreline of the sealing face on elbows. Do not measure the hose alone, because the fittings add a different length for each style. Lay the old assembly straight to measure it, and tell us the length, the two fittings, the hose bore and construction, and the elbow orientation if there are two elbows.

06What is elbow orientation on a hose assembly with two elbows?

It is the angle between the two elbows, measured looking along the hose from one end, and it must be specified or the assembly will arrive twisted to fit. Hold the assembly with the far elbow pointing straight away from you and read the angle, clockwise, to the near elbow: 0° means both point the same way. Fitting a wrongly oriented assembly by twisting the hose shortens its life. Send the angle, or a photo of the old assembly laid flat, with your enquiry.
