Parker A-LOK® double-ferrule compression fittings for instrument tubing — straight male connectors (tube-to-NPT and tube-to-BSP), female connectors, tube-to-tube unions, and 90° and 45° elbows in SS 316/316L. Tube OD 1/8" through 1" imperial; 6mm through 25mm metric. A-LOK front cutting ferrule bites into tube OD while back ferrule provides axial spring force — maintaining a leak-tight seal through thermal cycling and vibration. Working pressure up to 10,000 psi (689 bar) in 1/4" SS tube. ASTM A479 SS 316/316L body material. ASME B1.20.1 NPT threads. EN 10204 3.1 MTCs and CoCs supplied with every order. SAEP-347 compatible grade.
■ SAEP-347Parker A-LOK® equal tees, reducing tees, union crosses, in-line unions, reducing unions (1/4" to 3/8" and 1/2" to 1/4"), bulkhead unions for panel penetrations, and male elbow connectors. All in SS 316/316L. Bulkhead unions allow instrument tubing to pass cleanly through enclosure walls — most common in analyser sample conditioning cabinets and marshalling panels at Saudi Aramco instrumentation rooms. Reducing unions allow size transitions in instrument manifold headers without additional adapters. End caps and plugs for dead-ending impulse lines during commissioning and testing. All items carry full EN 10204 3.1 MTCs traceable to originating mill heat number.
■ SAEP-347Parker CPI™ (Compression, Pre-swaged Instrumentation) fittings offer a single-ferrule compression design and are widely used alongside A-LOK systems for general instrument tubing connections. CPI female connectors (tube-to-FNPT), male connectors (tube-to-MNPT), equal tees, branch tees with FNPT off-take, and unions are stocked in SS 316/316L and brass. Brass CPI fittings serve non-process instrumentation such as air systems, water utility lines, and general-service pneumatic control. SS 316/316L CPI fittings are used for corrosive and process-fluid instrument lines where a cost-competitive alternative to A-LOK double-ferrule is acceptable. Dimensions conform to ASTM A479 material and ASME B1.20.1 NPT thread standards.
■ SAEP-347Parker Push-Lok and PushTite push-to-connect fittings for pneumatic instrument air tubing — nylon, polyurethane, and PTFE tube OD 4mm to 16mm (metric) and 1/8" to 1/2" (imperial). One-touch tube insertion with collet-grip release tool for fast installation in pneumatic control panels, valve positioner signal tubing, and instrument air distribution headers. SS 316 and nickel-plated brass body options. Maximum working pressure: 10 bar (145 psi) at 20°C. Temperature range: -20°C to +80°C. Types include straight unions, 90° elbows, tees, Y-fittings, reducers, and bulkhead variants. Used at Saudi Aramco and SABIC for positioner air supply tubing and pneumatic control panel assembly.
Double-ferrule compression tube fittings in duplex stainless steel 2205 (UNS S31803/S32205) for instrument tubing systems in sour-service environments requiring NACE MR0175 / ISO 15156 compliance. Duplex 2205 offers a PREN (pitting resistance equivalent number) of approximately 35 versus 24 for SS 316L — providing significantly superior resistance to sulphide stress cracking and pitting in H₂S-containing process streams. Required for instrument impulse lines on sour-gas separators, H₂S-containing crude systems, amine absorbers, and sour water strippers at Saudi Aramco and SABIC facilities. Hardness ≤ HRC 22 per ISO 15156-3. Supplied with NACE MR0175 compliance statements and EN 10204 3.1 MTCs confirming duplex grade chemistry. Available by inquiry — typical 5–10 working day lead time.
Carbon steel double-ferrule compression fittings for hydraulic instrument lines and non-process tubing systems where stainless steel is not required — pressure gauge sensing lines on lube oil systems, hydraulic control systems on valves, and instrument air distribution where fluid compatibility allows carbon steel. Brass compression fittings (CPI and A-LOK equivalent) for non-process instrumentation — instrument air, cooling water sensing, and general utility gauge connections where ambient service conditions and non-corrosive media allow brass body and ferrule material. All brass fittings comply with ASTM B124 material standard. Carbon steel fittings supplied with EN 10204 2.2 certificates; SS and brass with EN 10204 3.1. PMI available on request for all grades.
Instrumentation tube fittings are mechanical compression connectors that form a repeatable, leak-tight seal on stainless steel instrument tubing without welding. Parker A-LOK® double-ferrule compression fittings in SS 316/316L have become the dominant specification at Saudi Aramco facilities because of their proven performance in impulse line service: a front cutting ferrule bites into the tube OD while a back ferrule provides axial spring force, maintaining seal integrity through thermal cycling and vibration. The 316L grade satisfies SAES-J-003 requirements for corrosion resistance in process instrumentation environments across the Kingdom's oil, gas, and petrochemical plants. Parker A-LOK fittings are listed in Saudi Aramco Approved Vendor Lists for instrumentation components and are interchangeable with Swagelok-dimensioned hardware already installed on operating plants, allowing mixed-lot maintenance without full replacement of tubing runs. Working pressures reach 10,000 psi (689 bar) in 1/4" OD tubing.
All items stocked in Jeddah. EN 10204 3.1 MTCs and CoCs supplied with every order. Contact us for part numbers, quantities, and lead times. Swagelok-compatible dimensions available across A-LOK and CPI series.

Saudi Aramco Engineering Standard SAES-J-003 (Instrumentation System Design) is the primary specification governing material selection for instrument tubing systems across all Aramco-operated facilities. It mandates 316L stainless steel seamless tubing to ASTM A269 for all process impulse lines, with double-ferrule compression fittings specifying a minimum wall thickness appropriate to the system design pressure and SAEP-347 inspection class. Instrument tubing sizes most frequently called up under SAES-J-003 are 1/4" OD × 0.035" wall for general impulse duty and 3/8" OD × 0.049" for heavier-flow sample conditioning lines. SAES-L-350 covers tube and fitting material selection for specific process fluid categories. Gulf Union Ozone stocks Parker A-LOK fittings that meet the dimensional and material requirements of SAES-J-003 and can supply full EN 10204 3.1 MTCs showing chemical composition, tensile data, and hydrostatic test results — the documentation package required at Saudi Aramco instrument inspection gates.

For instrument tubing systems in sour-service environments — wells producing H₂S above NACE MR0175 thresholds — 316L stainless steel compression fittings are still widely used on impulse lines but the fitting and tubing combination must demonstrate compliance with ISO 15156-3 to avoid sulphide stress cracking. For higher H₂S partial pressures, particularly in wet-gas separators and gas-injection systems, duplex stainless steel 2205 (UNS S31803/S32205) offers significantly superior resistance to pitting and stress corrosion cracking compared to 316L, with a PREN of approximately 35 versus 24 for standard 316L. Gulf Union Ozone can source duplex 2205 Parker-compatible tube fittings and ASTM A789/A790 duplex seamless tubing for sour-service instrument runs on request. All sour-service material is supplied with NACE MR0175 / ISO 15156 compliance statements and EN 10204 3.1 MTCs confirming hardness below HRC 22.
Gulf Union Ozone maintains safety stock of Parker A-LOK® and CPI™ fittings and SS 316/316L seamless tubing meeting the material specifications referenced in Saudi Aramco SAEP-347 for instrument tubing connections — the same material basis as SAES-J-003 impulse line systems throughout Aramco facilities.
