FEMALE COUPLING SST

Description & Features

Constructed from 316 stainless steel with a Buna-N seal, this Female Coupling Sst is part of the Aeroquip Hansen HK Series and is built to handle demanding hydraulic and fluid transfer applications across agriculture, construction, oil and gas, aerospace, and a broad range of industrial environments. The 3/8 BSPP end connection pairs with a push-to-connect interface, and the ball lock internal mechanism enables quick, tool-free coupling and disconnection in the field.

Certified to ISO 7241-1 Series B, the coupling is rated for flow up to 6 gallons per minute and carries a minimum working temperature of -40°F, making it suitable for cold-climate and heavy-duty service conditions. The two-way valve design supports reliable fluid control, and the stainless steel construction provides strong resistance to corrosion in chemical, food and beverage, and marine-adjacent applications. No safety locking mechanism is included by design on this configuration.

Product Questions & Answers (1)

Question by: Warren M on Jun 19, 2025, 7:37 PM
Will this hook up to standard hydraulic lines on my tractor, or do I need some kind of adapter?
Answer by: Customer Support on Jun 20, 2025, 9:12 PM
This coupling uses a 3/8 BSPP end connection, so you might need an adapter depending on what your tractor uses. It's made for quick connections, though, so swapping should be pretty easy.
