  • Holding up well and expectation for a long life.
Style: 3/8" SB1 Coupling
This fitting is holding up so far approaching 1 year. I know many will say the O rings will not hold up but the mini split hardware and electronics as produced today are not anything to brag about either. So I do not see this fitting as a compromise. I expect minimum of 5 years of life and will not be surprised to see 10 years or more. ... show more

Style: 3/8" SB1 Coupling
I ordered two of these 3/8 and 1/4... the 3/8 held but the 1/4 didn't seal and leaked so didn't use just ordered all new line sets
