At BOA we understand that hydraulic adaptors are an important part of a hose system, and because they come in a vast array of fitting thread types finding the right hydraulic hose adaptors can be challenging.
We supply a diverse range of hydraulic hose adaptors that meet international and industry standards with no compromise when it comes to the quality of workmanship.
And because we are more than just suppliers, we can help you find the right hydraulic fitting thread types, or work with you to set up a customised hydraulic hose management programme that includes a real-time inventory system to make sure you have the right hose adaptor when and where you need it.
The team at BOA has raised the bar when it comes to hydraulics, call or email one of our team today to find out more about how we can partner with you to save time and money with our unique #hydraulic_uptime solution.

BSP (British Standard Pipe) – BSP connections include two types of thread, BSP Parallel (BSPP) which are straight (or parallel) and BSP Tapered (BSPT). BSPT couplings seal on the thread and thread sealant is recommended. BSPP couplings seal by a 30° cone which seats with the seal in the female swivel. Where a BSPP male is being mated with a fixed female port sealing is accomplished using a bonded seal (Dowty Seal).
BSP threads have a 55° thread angle with a rounded crest, as opposed to a 60° thread angle and sharp crest on a NPT
JIC 37° Flare – JIC connections seal by the male flare contacting the female cone seat with the connection being held by the thread
ORFS – ORFS or ‘O’ Ring Face Seal connections use an ‘O’-ring housed in the face of the male and compressed against the face of the female with the connection being held by the thread.
Metric – The DIN Metrics 24° Cone System seals by the male 24° sealing angle cone seat connecting with the female 24° convex cone with O-ring. The connection is held by the straight metric thread. The DIN Metrics system has two series; The DKOL light series for pressure up to 250 bar and the DKOS heavy series for pressure up to 640 bar.
SAE O-Ring Flanges (Code 61, Code 62) – SAE flanges seal by an ‘O’-Ring seal housed in the flange head compressing against a flat female port. The flange is clamped in place by either a split or one-piece clamp secured by four bolts. SAE flanges come in two types with different nominal pressure ratings; Code 61 for up to 5000psi on 1/2″, 3/4″ & 1″, 4000psi on 1-1/4″ & 1-1/2″ and 3000psi on 2″. Code 62 for up to 6000 psi for all sizes.
Komatsu – Komatsu connections look similar to JIC except they have a 30° flare and use metric fine threads (1.5mm pitch). Komatsu connections seal on the 30° flare which is held by the thread.
JIS – JIS (Japanese Industrial Standard) has two thread types which both seal on a 30° flare, one type is BSP thread with an inverted flare and the other is metric JIS (M/MU) which uses a 1.5mm thread pitch on the first three sizes (14, 18, 22) and a 2mm thread pitch on the larger sizes (27, 33, 42,50,60). JIS with BSP threads are not interchangeable with BSP as the JIS flare is inverted.
NPT – NPTF (National Pipe Taper Fuel) males have a 30° cone and will mate with all NPT female types sealing either on the thread or the 30° cone. No thread sealant is required on NPT connections but can be used to prevent galling. NPT look nearly identical to BSP but are not compatible as they have a 60° thread angle as opposed to BSP’s 55° thread angle.
UNO – UN ‘O’-Ring thread is of the same type as JIC, however the UNO is not seated and has an o-ring for sealing. A UNO female port is chambered to seat the o-ring.
Karcher – Karcher connectors for use with pressure washers using Karcher style connections. The female is a 22mm swivel nut, the male (or gun end) is either a 9.8mm or 11mm stub insert with O-ring.
