From BSP to ORFS, have a read to find out about thread patterns!
There are many different variations of thread when it comes to hose fittings. We have compiled some information and measurement charts on a few of the more common threads that we see here at ABCo.
British Standard Pipe Thread or BSP is one of the most widely recognised thread patterns. Whilst most common in the UK, BSP has been adopted by many countries worldwide, particularly in Europe. There are two main types of BSP thread: British Standard Pipe Parallel Thread (BSPP) and British Standard Pipe Tapered Thread (BSPT).
Please see below for the pattern measurement chart.

Joint Industry Council Thread or JIC, is another popular thread commonly used for hydraulic systems. Being predominantly used in North America, JIC fittings have become increasingly popular throughout the global industrial and agricultural industries.

Learn all about the regulations regarding lifting equipment and how we can get your pit jack back up to standards.
You are required to regularly maintain and test your pit jack by the Lifting Operations & Lifting Equipment Regulations 1998 (LOLER).
In the UK, LOLER requires that lifting equipment such as pit jacks must be of adequate strength and stability. The regulations state that all lifting equipment should be fit for purpose, appropriate for the task, suitably marked and, in many cases, subject to statutory periodic 'thorough examination'. During this examination period, any defects (which are or could potentially become a danger to people) will be found and reported.
Lifting equipment must be thoroughly examined in a number of situations. Your equipment must be checked before the first use, if you install at another site or if it has been subject to conditions liable to result in danger. Following the examination, any defects can be identified and if so, a service can be booked.
Our Pit Jacks are always built using high-quality steels, ensuring strength and durability. Should you require a repair, we can offer a full factory service and complete refurbishment of your Pit Jack to ensure it complies with regulations above. Following the refurbishment, we will test your Pit Jack to confirm the performance and quality standards have been met.
Please contact us or visit Pit Jack Repair & Service for more information.

As well as our Pit Jack range, we design and manufacture high-quality products such as standard and bespoke hydraulic cylinders, high pressure pumps and power packs. All of which we can repair and service ourselves from our factory in Nottinghamshire.
Want to know how we repair hydraulic cylinders and replace hose assemblies? Explore our guide to discover all the ins and outs of our quick and efficient repair services available in Nottinghamshire and surrounding areas.
Since 1972, we have been using our specialist expertise to repair and test all types of cylinder, including double/single acting, displacement and multi stage cylinders. We can deal with many issues, from a broken seal or bent rod to a weld crack.
We also manufacture and assemble many variations of hose. These include 1 + 2 wire and multispiral, with fitting thread patterns from BSP and JIC to light/heavy series Metric styles.
We start the ram repair process by inspecting the cylinder and assessing the damage. Once we’ve diagnosed the initial problem, we then carefully strip the cylinder and carry out a detailed inspection of each component.
If the repair is straightforward - such as a seal replacement - then we proceed. If the damage is more complex, we quote for the repair or replacement of any damaged parts and, subject to customer approval, carry out the necessary repairs and re-assemble.
On completion, we pressure test on our test rig to ensure the cylinder performance and quality standards have been met. All our repairs are guaranteed.
We can manufacture a hose based on given specifications or you can drop off the damaged hose to us and we’ll produce a high-quality replacement as per sample. Once we have understood your requirements, we will then manufacture the hose to suit and pressure test on our test rig.
Here at ABCo, we want to be certain that you walk away with a functioning cylinder or hose. Safety is a number one priority and we always take the risk-free approach to a repair to maximise lifespan and performance. As stated we can build to best suit your requirements. All repair work and servicing is done in an efficient manner and the highest standard of quality. Simply enquire today via telephone, email or online our contact form.
Subject to the work required, we offer a quick turnaround. We aim to complete large repairs in a few days and for smaller repairs in under 24 hours.
The cost will always depend on the level of work needed. Once we have inspected the cylinder or hose and understand all the factors (such as materials required) you’ll receive a quote.
