Overview

The rubber (CPE) crimp style fitting is a two-piece hose end designed to terminate rubber hose professionally. A machined body carries the hex nut for tightening and the threaded or barbed connection to the system, while a separate crimp ferrule is compressed over the hose once the fitting is inserted. The range covers straight, 45° and 90° bodies from HF-6103 to HF-6120, covering AN -3，-4，-6, -8, -10, -12 ， -16 and -20 hose. These fittings are used wherever rubber hose needs a durable, leak-free termination in fuel, oil, coolant, air and hydraulic systems, in workshops and on production lines.

How a Crimp Fitting Works

The insert end of the body is pushed inside the hose bore, where its barbs grip the inner wall and provide the seal surface. The ferrule then closes around the outside of the hose and is crimped down with controlled hydraulic force, compressing the hose wall evenly between ferrule and insert. Because the load is distributed around the full circumference rather than at a few points, the joint resists pressure spikes, vibration and pull-off loads that loosen clamp-style connections over time. Crimped assemblies also keep a low, neat profile and cannot be tampered with or accidentally released in service.

Part Number System

The part number makes selection simple and repeatable. HF-61 identifies the fitting family; the following two digits give the hose size — 03,04,06, 08, 10, 12,16 or 20 for AN-3,-4, -6, -8, -10, -12 ,-16 and -20— and the suffix gives the angle: 0 for straight, -45 for a 45° elbow and -90 for a 90° elbow, -180 for a 180° elbow.A single line of the catalogue therefore covers every size and angle in the family, which reduces ordering mistakes, simplifies stock keeping for distributors and lets a workshop specify a replacement assembly accurately from the old hose alone.

Material Options: AL, SS and ST

Three material options cover different duties. Aluminum (AL) gives light weight and good corrosion resistance and is the usual choice for performance and motorsport builds where weight and appearance matter. Stainless steel (SS) offers the highest corrosion resistance and is preferred for brake lines, marine use and harsh environments where the fitting must survive salt and moisture. Steel (ST) provides a cost-effective option for general industrial and workshop use. Because the body and ferrule are matched as a set, the assembly performs consistently whatever material is selected.

Angle Options

Choosing the right angle is often what makes an installation clean rather than merely possible. Straight bodies suit direct runs where the hose approaches the port in line. The 45° elbow handles intermediate direction changes and gradual transitions around accessories. The 90° elbow is the standard solution at filters, pumps, rails and bulkheads where space is tight and a straight fitting would force the hose into an unacceptable bend. Using the correct angle shortens hose runs, avoids kinking at the connection and reduces the stress that leads to early failures.

Crimping and Assembly

Assembly begins with a square cut: the hose is cut cleanly to length so the end sits flat against the shoulder of the fitting. The body is inserted fully, the ferrule is positioned over the hose, and the assembly is placed in the crimping machine with the correct die for that size. Crimp diameter is set on the machine so every assembly is identical, which is what makes results repeatable between operators and batches. After crimping, the assembly is inspected and pressure-tested where required before it goes into service.

Applications

These fittings serve fuel supply and return lines, oil cooler and turbo oil lines, coolant and heater circuits, air and pneumatic lines, and general hydraulic hose assemblies. They are used by performance workshops building custom lines, by repair shops replacing damaged hoses, by equipment dealers making implement hoses on site, and by manufacturers supplying complete assemblies to OEM programs. In each case the same fitting family covers the common hose sizes, so one stock line supports many service jobs and keeps inventory simple.

Quality and Inspection

Bodies are machined to consistent tolerances so that the insert fits the hose bore and the ferrule seats correctly every time. The materials and finishes are selected for corrosion resistance in service, and each batch is produced under the same process controls. The body and ferrule are supplied as a matched set, because a mismatched pair is the most common cause of a leaking or weak crimp. Before shipment, fittings are inspected for thread quality, finish coverage and dimensional accuracy so that the assembly performs as expected on the first crimp.

Customization and Support

Custom sizes, angles, materials and finishes are available for OEM and bulk programs, together with custom packaging and private labeling for distributors. Fittings can be supplied loose, as kits with ferrules, or as finished hose assemblies crimped and tested to the customer specification. Our team provides technical data and samples so that a customer can confirm the correct body, ferrule and crimp setting before committing to volume. If a requirement falls outside the standard range, we are glad to review it and advise on the closest practical solution. Fittings are packed in quantities that suit both counter sales and production lines, with labels showing the part number, size, angle and material so the correct item is picked without guesswork.

Ordering & Packaging

Fittings can be ordered individually, as matched sets, or as complete assemblies produced and tested to your specification. Standard items ship from stock, while custom sizes, angles and finishes are produced to order, and samples are available for evaluation before a volume order is placed. Packaging can be tailored to distributor or production requirements, including bulk cartons and private labeling, so that goods arrive ready for the shelf or the assembly line.
