Cable protection hoses

Reiku systems in plastic and metal, IP-rated.

Reiku cable protection hoses protect wiring against moisture, dust, oil and mechanical damage. Hose and gland form an IP-rated system together; the inner diameter sets the fill ratio, the bend radius decides whether the hose may follow a moving axis.

All about cable protection hoses

Technical guidance from our engineers: how to choose, what to measure and where installations fail in practice.

Nominal width, inner diameter and fill ratio

Protective hoses are designated by a nominal width (NW) that roughly matches the inner diameter. Add up the outer diameters of all cables, multiply by 1.3 to 1.5 for movement and pulling, and pick the next NW above that. A hose chosen too wide rattles and chafes internally; one chosen too tight makes pulling in almost impossible and sharply increases bending force.

Profile, material and protection rating

A corrugated profile is light and flexible; a smooth or reinforced hose withstands more pressure and mechanical impact. Polyamide is the workhorse for machine building, polypropylene is more chemically resistant, and metal-reinforced or glass-braided versions handle high temperatures. The IP rating always applies to the complete system: hose plus gland plus a correctly tightened seal.

Glands and installation

Match the gland to the hose: same NW, same manufacturer series and a metric or NPT thread that suits the enclosure wall or motor housing. Use the correct cut-out diameter with a lock nut or sealing washer, and on moving axes always let the hose follow the manufacturer's bend radius — no tighter. Hose from the reel may be cut to length; cut square so the gland grips properly.

Series in cable protection hoses

Every series has its own page with the full size range, technical data and documentation.

Frequently asked questions

The questions our technical desk receives most often about this category.

How do I choose the right size of cable protection hoses?

Start with the fill: the thickest cable sets the minimum inner height, the sum of all diameters plus 10% clearance sets the inner width. Then pick a bend radius of at least ten times the thickest cable diameter. Filter on those three values on the left and only suitable articles remain.

What is the lead time and when do you ship?

Articles marked 'in stock' ship the same working day when ordered before 15:00 CET. Articles 'on request' are made to order at the manufacturer; the lead time is stated in the quotation, typically 5 to 15 working days.

Do I get technical documentation and CAD files?

Yes. Every article lists a datasheet, a manual and a STEP file for your 3D model. All are free to download, no account required.

Are the prices volume prices?

The price shown is per unit. From the indicated tier quantity onwards the lower price applies automatically and is calculated in the cart. Use the toggle at the top to show prices including or excluding VAT.

Which gland matches which hose size?

The gland follows the hose's nominal width (NW) and manufacturer series. NW17 therefore takes an NW17 gland from the same series; the thread size (M, PG or NPT) is chosen for the enclosure wall. Mixing hoses and glands from different manufacturers almost always leaks.

Can a protective hose run inside a cable carrier?

Yes, provided the hose meets the carrier's bend radius and has its own chamber. Count the hose's outer diameter in the fill ratio; it is considerably larger than the cable itself.

Can hose from the reel be cut to length?

Yes, we supply per metre from the reel and cut to the length you specify. State the length per piece so you receive continuous pieces rather than remnants.
