Push-Pull Connector for Oil and Gas Drilling 2026: S6TL4FN-SMSM19-D920 and S6ZL4FN-SFPM19-R340 with 316L Stainless Housings for LWD/MWD Instruments for Saudi Arabian Client
The S6TL4FN-SMSM19-D920 is a 4F push-pull connector for oil and gas drilling — a 19-pin plug with a custom 316L stainless steel housing, mated to the S6ZL4FN-SFPM19-R340 hermetic socket, engineered for LWD/MWD logging instruments that face heavy mud, acidic crude oil and hydrogen sulfide downhole, with gold-plated contacts. Every specification in this guide is backed by the oilfield interconnect engineering of Spring Technology.
Pain point: Wiring LWD/MWD geological exploration instruments in oil and gas operations — where equipment from downhole testing tools near the drill bit to surface data acquisition cabinets operates in heavy mud and highly corrosive substances such as acidic crude oil and hydrogen sulfide?
Core answer: For a Saudi Arabian client, Spring Technology supplied a push-pull connector for oil and gas drilling: the S6TL4FN-SMSM19-D920 plug and the S6ZL4FN-SFPM19-R340 socket, featuring custom 316L stainless steel housings, for use in LWD/MWD (Logging/Measurement While Drilling) geological exploration instruments during oil and gas exploration and refining operations. In these applications, the equipment — ranging from downhole testing instruments near the drill bit to surface data acquisition cabinets — operates in environments characterized by heavy mud and exposure to highly corrosive substances, such as acidic crude oil and hydrogen sulfide. The physical strength and chemical resistance of 316L stainless steel are essential for performance in these demanding conditions.
1. Technical Parameters & Engineering Standards

2. Oil and Gas Connector Design Highlights
Oilfield tools face the most corrosive environments in industrial electronics. The design highlights below are why this push-pull connector for oil and gas drilling is specified for LWD/MWD systems:
- 316L stainless steel housing — the custom 316L housings deliver the physical strength and chemical resistance essential for downhole and refinery conditions.
- Hydrogen sulfide resistance — engineered for exposure to highly corrosive substances such as acidic crude oil and hydrogen sulfide.
- Heavy mud tolerance — built to operate in heavy drilling mud from the drill bit to surface cabinets.
- 19-pin logging link — carries the measurement and telemetry channels of LWD/MWD instruments.
- Hermetic socket side — the ZL hermetic socket seals the instrument interior against mud and fluids.
- Gold-plated contacts — stable signal paths for logging data in extreme conditions.

4. Applications: LWD/MWD and Oilfield Data Systems
From the drill bit to the data cabin, oilfield instruments need corrosion-proof connections. This push-pull connector for oil and gas drilling keeps logging data flowing.
4.1 Downhole Testing Instruments
Near the drill bit, downhole testing instruments face heavy mud and corrosive well fluids. The 316L housings and hermetic sealing keep the logging link intact at depth.
4.2 LWD/MWD Geological Exploration
Logging and measurement while drilling instruments rely on the 19-pin link to carry measurement and telemetry data during exploration and refining operations.
4.3 Surface Data Acquisition Cabinets
At the surface, data acquisition cabinets in refinery and rig environments benefit from the same corrosion-resistant connector family.
