Helpful for Model Matching:
- Full BKC code and tube OD AND ID
- Published pairing and exact metric/PT thread
- Tube temperature rating and actual medium
- Body/cap construction and installation clearance
- Quantity and destination
- Own OD/ID/thread row including explicit ID alias notes
- Locking cap versus threaded body wrench surfaces
- Mixed body/cap materials
- Tube temperature and medium confirmation
Catalogue Technical Specifications
| Actual connection mechanism | Straight locknut tube connector: put locking cap over tube, insert tube into body, tighten cap; loosen cap before tube removal. Not a push-in release-button fitting or a panel locknut fitting. |
| OD AND ID pairings | 04 OD/25 ID(2.5mm):M3/M5/01;06 OD/04 ID:01/02/03;08 OD/05 ID or06 ID(5.5 or6mm):01/02/03;10 OD/65 ID or75 ID(7.5 or8mm):02/03/04;12 OD/08 ID or09 ID(9 or10mm):02/03/04. 24 codes. ID aliases are explicit dimension notes, not permission for arbitrary ID. |
| Complete code and thread | BKC[OD][ID]-[thread]-S. M3=M3×0.5,M5=M5×0.8;01/02/03/04=PT1/8,1/4,3/8,1/2. Blank pipe-thread type=PT. No colour D,G/NPT or final316 suffix published. BKC-S-06-01 omits ID and is not a complete published model. |
| Pressure and tube temperature | Operating0–1MPa; proof3MPa separately; negative pressure−750mmHg(10Torr). Connector ambient/fluid0–150°C. Source explicitly requires checking tube temperature resistance first for high-temperature use. This does not rate every nylon/PU tube to150°C; tube material and chemical compatibility need confirmation. |
| Mixed materials | Current English section labels body stainless steel and locking cap aluminium alloy; ordering S=SUS304. Do not describe the complete connector as all304 or corrosion-proof. |
| Dimensions and wrench surfaces | Own24 dimension rows: L,C,K,G cap flats,H body flats and weight. Mount threaded body using body wrench flats, not the cap. Chinese supplement explicitly warns not to apply wrench on locking cap for threaded installation. Installation torque/depth not numerically published. |

About BKC-S
AirTAC BKC-S straight tube connectors use a locking cap and require both tube outer and inner diameter. Match only published OD/ID/thread combinations, then send the full code or tube photo for quotation. SUS304 body with aluminium-alloy cap; verify tubing temperature and medium separately.
Matching Questions
Can I identify BKC-S from tube outer diameter alone?
No. The ordering code includes tube OD and ID, thread and final-S. Send the full marking or tube OD/ID and installation photo. Verify tube temperature suitability before applying connector temperature data.
