Stainless Steel 316 BSPP Hex Cap

A 316 stainless steel female threaded hex cap used to blank off or seal a 1¼ inch BSPP male pipe thread. The hexagonal body allows quick installation with a standard spanner, and the parallel BSPP thread (designated "G" thread to ISO 228-1) provides a secure, leak-free termination. Cast from CF8M 316 stainless steel, this fitting offers strong resistance to corrosion, chlorides, and harsh process media, making it well suited to both indoor and exposed outdoor environments.

The 150 lb pressure rating and durable 316 grade material make this cap a reliable choice across a wide range of industrial, marine, and process piping systems where a clean, permanent pipe end seal is required. Approximate weight: 0.147 kg.

• Water treatment plants
• Chemical processing facilities
• Food and beverage production
• Pharmaceutical pipework
