Ball-lock quick coupler in bronze — threaded female body and male plug
TECTUL · Dispatch across Colombia · Exports to Central & South America
Two-piece quick coupler retained by steel balls: the female half has a knurled sliding sleeve (retracts the balls to release) and external male thread; the male half is a smooth plug with a groove for the balls and external male thread at its base, plus a sealing O-ring. It is a generic ball-lock pattern, distinct from the named "industrial interchange"/Foster or Chicago patterns (see the FT-TC-RAC-FOSTER-BRONCE-001 and FT-TC-RAC-CHICAGO-001 sheets): no published interoperability standard was confirmed for this specific reference. Typically used on pressure-washer accessories and medium-pressure air or water lines.
Important: Before using these data in engineering, design or installation decisions on systems exposed to mechanical, pressure, rupture, fatigue, impact or water-hammer risk, it is essential to read the technical notice and limitation of liability at the end of this sheet.

| Material | Bronze (body) · stainless steel (balls, sleeve and male plug shaft, per photograph) |
| Ends | External male thread on both halves; O-ring seal on the male shaft |
| Mechanism | Insert the male until the balls lock it; slide the knurled sleeve back to release |
| Typical application | Pressure-washer accessories, irrigation lances, medium-pressure air or water lines |
| Interoperability standard | Not confirmed for this reference; do not assume compatibility with the named Foster/industrial interchange or Chicago patterns without physical verification |
| Dimensions and pressure rating | Confirmed on quotation — no manufacturer dimensional or pressure sheet available |
2. Frequently asked questions
Does this coupler connect to a Foster-type or Chicago-type one?
Do not assume it does without physical verification. Unlike Foster (industrial interchange, ISO 6150-B) or Chicago (2-lug claw), this ball pattern has no confirmed interoperability standard for this reference; it may or may not be compatible with other brands.
Is it suitable for pressure-washer water pressure?
That is its typical application per the photograph and catalog description, but the exact pressure rating is not published; confirm with the supplier before using it near your equipment's pressure limit.
3. Application notes
Feasibility
Suitable for pressure-washer accessories and medium-pressure air or water lines where certified cross-brand interoperability is not required. Do not specify in systems requiring a named pattern (Foster, Chicago) without verifying physical compatibility.
Installation
Insert the male until the ball lock is felt. Seal the external male thread with PTFE tape or a compatible sealant before installing on hose or equipment. To disconnect, slide the sleeve back and withdraw the male.
Design
Confirm the pressure rating and exact dimensions with the supplier before specifying. Verify physical compatibility if you need to interoperate with another brand's coupler.
4. Technical notice and limitation of liability
The pressures, dimensions, weights and other characteristics in this sheet are theoretical calculation values obtained from nominal properties published in the standards cited (ASME B36.10-2022, ASME B31.3-2024, ASTM A106/A106M-19a, ASTM A53/A53M-24, API Spec 5L 46th ed.). They guide selection; they are not a certificate of conformity for any given lot.
The actual behavior of each lot varies with manufacturing — wall tolerance (up to −12.5%), out-of-roundness, residual stresses — and with the raw material — chemical composition within the ranges the standard allows, heat-to-heat differences. To certify a lot, the tests defined by its product standard are required: tensile test, flattening test and hydrostatic test, documented in the manufacturer's mill test certificate (MTC), which TECTUL supplies upon request; testing of the lot in an independent laboratory can also be arranged.
These values must not be used as the sole criterion in critical or safety applications, or wherever failure of the line may compromise people, property or the environment: in such cases the design belongs to the project's responsible engineer under the applicable code (ASME B31.3, B31.1 or the one governing the installation), with the design temperature, corrosion allowance and load cases of the actual service. Before deciding with these data, consult our technical team.
