Precision Gaskets in China for Your Industrial Machinery Needs

Kaxite manufactures RX ring joint gaskets on CNC equipment to ASME B16.20 and API 6A. The RX profile is listed for pressures up to 5,000 PSI and is interchangeable with R-oval or R-octagonal rings on API 6B flanges. The page lists a material table with hardness and temperature ranges: soft iron 90 HB and -60 to 500°C, low carbon steel 120 HB and -40 to 540°C, SS304/SS304L 160 HB and -250 to 540°C, SS316/SS316L 160 HB and -200 to 815°C, SS321/SS347 160 HB and -200 to 870°C, SS410 170 HB and -200 to 850°C, 5Cr-0.5Mo 130 HB and -29 to 650°C, Inconel 600 150 HB and -100 to 1095°C, and Incoloy 825 150 HB and -100 to 1095°C. For reference, the same page lists R-oval up to 1000 PSI and BX for 6BX flanges and 16BX hubs at 5,000-20,000 lbs; those are not RX ratings. MOQ, sample lead time, bulk lead time, OEM/ODM scope and certificate scope are not stated in the body and should be confirmed on inquiry.

Kaxite manufactures octagonal ring joint gaskets — a machined solid metal ring with an octagonal cross-section and 23° ± 0.5° flat face angle on each side, seated into the RTJ groove of a ring-type joint flange to provide a two-face metal-to-metal seal. The 23° angle is the reason octagonal rings seal tighter than oval rings on new or freshly machined grooves: the two faces bed into the groove simultaneously instead of on one line of contact per side. Materials: soft iron (120 HB max), F5 low carbon steel (130 HB max), SS304/304L/316/316L/321/347/310, 3CR12, duplex, Monel 400, Inconel 600/625/X-750, Incoloy 800/825, Hastelloy B2/C276, Nickel 200, titanium, copper, zirconium. Sizes R11–R105 per ASME B16.20, plus API 6A 6B and BX patterns. Temperature -200°C to +850°C, pressure up to 20,000 psi. MOQ 5 pcs, lead time 7–15 days, MTC EN 10204 3.1 issued with every shipment.

Kaxite manufactures oval ring joint gaskets (Oval RTJ) — a machined solid metal ring with an elliptical cross-section, seated into the groove of a ring-type joint flange to form a metal-to-metal seal. Oval rings are the original RTJ profile and are used where the flange groove can be re-cut or where slight misalignment between flanges must be tolerated; for new flanges with a fresh groove, the octagonal profile is often preferred because it seats on two faces instead of one line contact. Materials: soft iron, low carbon steel (F5), SS304, SS304L, SS316, SS316L, SS321, SS347, 310, 3CR12, duplex, Monel 400, Inconel 600/625/X-750, Incoloy 800/825, Hastelloy B2/C276, Nickel 200, titanium, copper, zirconium. Built to API 6A, ASME B16.20, API 605, ASME B16.47 Series A/B, BS 1560, BS 4504, DIN, JIS, NF, MSS SP-44. MOQ 5 pcs, 7–15 day lead time.
